Select Continue to move to the Kit Selection page.

One sequencing kit can be selected as well as one or more expansions. If a sequencing kit does not have any associated expansions, no expansion options will appear.

The filter options may be used to find the kit used. For example, click DNA to filter for DNA sequencing kits.

For control runs, there is a Control checkbox which only filters for the control experiments of the kits. This will automatically set the sequencing parameters for a control run. Note: Run length will be reduced to 6 hours for control experiments.

Click Continue to navigate to the run configuration page.

At the top of the run configuration page you will see an overview of your experiment set-up and identifiers inlcuding:

• Experiment name: defined by user.
• Positions: Flow cell position(s) being used in the sequencing experiment, and the associated sample IDs for the position(s).
  Note: If using multiple flow cells, click "show details" to open a window displaying all the positions used and the associated sample IDs.
• Flow cell type: automatically detected by the MinKNOW software.
• Sequencing kit: the sequencing kit used for DNA/RNA library preparation, user-defined.

The basecalling option is on by default to perform real-time basecalling. This can be switched off and basecalling performed post-sequencing.

Note: If basecalling is disabled, barcoding and alignment will not be performed during sequencing.

Modified bases is off by default. This can be switched on to use the CpG context models and basecall 5mC and 5hmC.

To specify your basecall model and modified bases, click the Edit icon to open basecalling options dialogue box.

Barcoding options are only available when a barcoding sequencing kit or expansion has been selected. Barcoding can be switched off and performed post-sequencing.

To specify the barcoding options, click the Edit icon to open the barcoding options dialogue box. From here, barcode trimming and custom barcode selection can be defined.

By default, barcoding trimming is off. This can be enabled to remove barcodes from demultiplexed reads. Please note, some primer sequences may also be trimmed together with the barcodes.

By default, custom barcode selection is off. This can be enabled to only select for specified barcodes used in your library preparation for the current sequencing run.

Note: Specifying barcodes must be entered as:

• Individual numbers.
• Numbers separated by commas.
• Range of numbers separated by a dash.
• A combination of numbers and ranges, separated by commas.

Some sequencing kits place barcodes on both ends of the read. By default, the barcode both ends feature is off. If this feature is enabled, the barcode will only classified if a barcode above the minimum barcode score is present at both ends of the basecalled read.

Note: For barcoding to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

To use alignment during sequencing, upload an alignment reference file as a .fasta or .mmi file. We recommend uploading a reference locally on bacterial-sized genomes. Uploading a file can take a few minutes and is compute-dependent.

A reference file can contain multiple entries in the same file (e.g. multiple chromosomes) and alignment hits from these files are used to populate the alignment graphs which can be viewed on the GUI.

A BED file can also be uploaded alongside the reference when there is a specific interest in a particular region of the reference (e.g. specific gene in a chromosome). Alignment hits from BED files will be highlighted in the sequencing .txt file generated in the data folder. Click Edit options to open a dialogue box to upload a BED file.

Note: For alignment to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

Enabling adaptive sampling will allow you to enrich or deplete specific sequences from your aligned seuqencing data.
For our barcoding kits, the barcode balancing feature is also available using adaptive sampling through the "beta" features in MinKNOW.

More information on this feature can be found in our adaptive sampling documentation.

This feature allows you to set up the rules to define when a sequencing run will stop. If multiple rules are set up, the first rule met will stop the run.

Click the Edit icon to open the options.

Run limit

This rule must be defined based on run time length in hours or when a flow cell is end of life and has no more sequencing pores available.

Use the drop-down menu to choose:

• "Time equals" and hours
• or "Flow cell is" which will automatically be set as "End of life".

Flow cell data target

This rule can be used to define a target amount of data to reach before a sequencing run is stopped. This can be specified for either estimated or basecalled bases and your data target will be available to view on the experiment graphs to allow you to monitor data progress.

Please note, basecalling must keep up with data output in real-time. If the device or basecall model will not keep up and reach the target output before the run limit rule is met, we recommend using the "Estimated bases" option. However, if your experiment will not reach the target data before the end of the experiment as defined by the run limit rule, you will be warned by the UI.

Use drop-down menu to select for "Estimated bases equal" or "Basecalled bases equal" and input the value in either Gb or Mb.

The output section provides variables for data output including file name, location and format.

Click the Edit icon to open the options.

Output settings:

Data saved as:

Check the name of the output file for the data.

Output location:

Confirm the location for the output data file. Click the file path name to open a pop-up to alter file path or create a new file.

Click Choose location on the pop-up to confirm new file location.

Output location storage capacity:
A bar indicator is displayed below the selected data output file location. This bar will display red when the disk space used reaches more than 80% of the total available disk space. Otherwise, the bar will display green. Below the bar, you can see how much drive space is available.

Basecalled output options:

Confirm output file type and file compression using the checkboxes.

Note: Below, reads per file can be changed for both raw reads and basecalled reads, but take note:

• Fewer reads per file: reads become more quickly available. However, too few reads per file means MinKNOW may not keep up with writing out files in real-time.
• More reads per file: reduces the number of files especially for amplicon/cDNA experiments that produce a large number of reads. Some downstream analysis tools may have an upper limit on the uploaded file size.

Basecalled output type:
Output file type can be selected between .FASTQ or .BAM files. The .FASTQ will be on as default if basecalling in real-time.

File output frequency can be adjusted for basecalled files based on two options:

For barcoding runs, basecalled reads are split into files by barcode by default.

Gzip compression of FASTQ files is on by default of basecalled reads. Note: FASTQ Gzip files may prevent some downstream informatics applications.

Raw reads output options:

Raw reads: Raw reads output can be saved as .POD5 or .FAST5.

• For Kit 14 chemistry and SQK-RNA004, .POD5 is the default file output. The .POD5 output generates files hourly.
• The .FAST5 output file is the default format for our previous and "legacy" chemistry kits. The.FAST5 output produces files for every 4000 reads.

.POD5 is a Nanopore-developed file format which stores Nanopore data in a more accessible way and can be used as an alternative to FAST5 output. This output also writes data faster, uses less compute and has smaller raw data file size.

We recommend keeping the default settings.

Raw reads split by barcode: Raw read files generated in the .POD5 format can now be split by barcode (if using one of our barcoding sequencing kits.
Please note, this feature is turned off by default and not available for .FAST5 files.

Filtering options can be used to determine which reads are classed into pass or fail files. These options may also be used to determine which predefined reads, read lengths and Qscore during basecalling can be split out in some live graphs.

Click the Edit icon to open the filtering options:

Use the GUI to alter Qscore and to define minimum and maximum readlength for a pass read, if required.

From here, you will see a progress bar below the flow cell to show the progression of the sequencing script.

In some cases, the device will take a few minutes before starting a sequencing run if an alignment reference file is used. A progress bar will show the progress before sequencing begins.

Flow cell health will be displayed after the first pore scan.

Below are recommended troubleshooting tips if there are unexpected differences in pore numbers:

• If there is a significant reduction in active pores in the first pore scan, restart MinKNOW.
• If the numbers are still significantly different, close down the host computer and reboot.
• When the numbers are similar to those reported at the end of the flow cell check, restart the experiment. There is no need to load any additional library after the restart.

This is only necessary if you want to stop your run before the end of the set run time.

Confirm to stop experiment by clicking:

• Stop sequencing which will start catch-up basecalling
• or Stop sequencing and basecalling which will stop both sequencing and basecalling immediately.

A run report containing information about the sequencing run and performance graphs can be generated manually by clicking Export run report and selecting which experiment to export to html.

Run reports are automatically generated for Flongle running on MinION Mk1C and MinION Mk1B running on Linux. However, for MinION Mk1B running on Windows or Mac, the run reports need to be manually generated.

For more information about the run report, please see the Run report section of this document.

A pore activity .csv file is also generated for every run.

The report and .csv files are saved to the same folder as the .fast5 and .fastq read files e.g. :\data\experiment\sample_ID\ for MinION Mk1B.

Ensure the experiment name and sample ID does not contain any personally identifiable information.

Note: If sample ID is not filled in, there will be no sample ID in the folder structure.

To use previously saved settings, please see the "Save sequencing run settings" page of this protocol.

Select Continue to move to the Kit Selection page.

One sequencing kit can be selected as well as one or more expansions. If a sequencing kit does not have any associated expansions, no expansion options will appear.

The filter options may be used to find the kit used. For example, click DNA to filter for DNA sequencing kits.

For control runs, there is a Control checkbox which only filters for the control experiments of the kits. This will automatically set the sequencing parameters for a control run. Note: Run length will be reduced to 6 hours for control experiments.

Click Continue to navigate to the run configuration page.

At the top of the run configuration page you will see an overview of your experiment set-up and identifiers inlcuding:

• Experiment name: defined by user.
• Positions: Flow cell position(s) being used in the sequencing experiment, and the associated sample IDs for the position(s).
  Note: If using multiple flow cells, click "show details" to open a window displaying all the positions used and the associated sample IDs.
• Flow cell type: automatically detected by the MinKNOW software.
• Sequencing kit: the sequencing kit used for DNA/RNA library preparation, user-defined.

The basecalling option is on by default to perform real-time basecalling. This can be switched off and basecalling performed post-sequencing.

Note: If basecalling is disabled, barcoding and alignment will not be performed during sequencing.

Modified bases is off by default. This can be switched on to use the CpG context models and basecall 5mC and 5hmC.

To specify your basecall model and modified bases, click the Edit icon to open basecalling options dialogue box.

Barcoding options are only available when a barcoding sequencing kit or expansion has been selected. Barcoding can be switched off and performed post-sequencing.

To specify the barcoding options, click the Edit icon to open the barcoding options dialogue box. From here, barcode trimming and custom barcode selection can be defined.

By default, barcoding trimming is off. This can be enabled to remove barcodes from demultiplexed reads. Please note, some primer sequences may also be trimmed together with the barcodes.

By default, custom barcode selection is off. This can be enabled to only select for specified barcodes used in your library preparation for the current sequencing run.

Note: Specifying barcodes must be entered as:

• Individual numbers.
• Numbers separated by commas.
• Range of numbers separated by a dash.
• A combination of numbers and ranges, separated by commas.

Some sequencing kits place barcodes on both ends of the read. By default, the barcode both ends feature is off. If this feature is enabled, the barcode will only classified if a barcode above the minimum barcode score is present at both ends of the basecalled read.

Note: For barcoding to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

To use alignment during sequencing, upload an alignment reference file as a .fasta or .mmi file. We recommend uploading a reference locally on bacterial-sized genomes. Uploading a file can take a few minutes and is compute-dependent.

A reference file can contain multiple entries in the same file (e.g. multiple chromosomes) and alignment hits from these files are used to populate the alignment graphs which can be viewed on the GUI.

A BED file can also be uploaded alongside the reference when there is a specific interest in a particular region of the reference (e.g. specific gene in a chromosome). Alignment hits from BED files will be highlighted in the sequencing .txt file generated in the data folder. Click Edit options to open a dialogue box to upload a BED file.

Note: For alignment to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

Enabling adaptive sampling will allow you to enrich or deplete specific sequences from your aligned seuqencing data.
For our barcoding kits, the barcode balancing feature is also available using adaptive sampling through the "beta" features in MinKNOW.

More information on this feature can be found in our adaptive sampling documentation.

This feature allows you to set up the rules to define when a sequencing run will stop. If multiple rules are set up, the first rule met will stop the run.

Click the Edit icon to open the options.

Run limit

This rule must be defined based on run time length in hours or when a flow cell is end of life and has no more sequencing pores available.

Use the drop-down menu to choose:

• "Time equals" and hours
• or "Flow cell is" which will automatically be set as "End of life".

Flow cell data target

This rule can be used to define a target amount of data to reach before a sequencing run is stopped. This can be specified for either estimated or basecalled bases and your data target will be available to view on the experiment graphs to allow you to monitor data progress.

Please note, basecalling must keep up with data output in real-time. If the device or basecall model will not keep up and reach the target output before the run limit rule is met, we recommend using the "Estimated bases" option. However, if your experiment will not reach the target data before the end of the experiment as defined by the run limit rule, you will be warned by the UI.

Use drop-down menu to select for "Estimated bases equal" or "Basecalled bases equal" and input the value in either Gb or Mb.

The output section provides variables for data output including file name, location and format.

Click the Edit icon to open the options.

Output settings:

Data saved as:

Check the name of the output file for the data.

Output location:

Confirm the location for the output data file. Click the file path name to open a pop-up to alter file path or create a new file.

Click Choose location on the pop-up to confirm new file location.

Output location storage capacity:
A bar indicator is displayed below the selected data output file location. This bar will display red when the disk space used reaches more than 80% of the total available disk space. Otherwise, the bar will display green. Below the bar, you can see how much drive space is available.

Basecalled output options:

Confirm output file type and file compression using the checkboxes.

Note: Below, reads per file can be changed for both raw reads and basecalled reads, but take note:

• Fewer reads per file: reads become more quickly available. However, too few reads per file means MinKNOW may not keep up with writing out files in real-time.
• More reads per file: reduces the number of files especially for amplicon/cDNA experiments that produce a large number of reads. Some downstream analysis tools may have an upper limit on the uploaded file size.

Basecalled output type:
Output file type can be selected between .FASTQ or .BAM files. The .FASTQ will be on as default if basecalling in real-time.

File output frequency can be adjusted for basecalled files based on two options:

For barcoding runs, basecalled reads are split into files by barcode by default.

Gzip compression of FASTQ files is on by default of basecalled reads. Note: FASTQ Gzip files may prevent some downstream informatics applications.

Raw reads output options:

Raw reads: Raw reads output can be saved as .POD5 or .FAST5.

• For Kit 14 chemistry and SQK-RNA004, .POD5 is the default file output. The .POD5 output generates files hourly.
• The .FAST5 output file is the default format for our previous and "legacy" chemistry kits. The.FAST5 output produces files for every 4000 reads.

.POD5 is a Nanopore-developed file format which stores Nanopore data in a more accessible way and can be used as an alternative to FAST5 output. This output also writes data faster, uses less compute and has smaller raw data file size.

We recommend keeping the default settings.

Raw reads split by barcode: Raw read files generated in the .POD5 format can now be split by barcode (if using one of our barcoding sequencing kits.
Please note, this feature is turned off by default and not available for .FAST5 files.

Filtering options can be used to determine which reads are classed into pass or fail files. These options may also be used to determine which predefined reads, read lengths and Qscore during basecalling can be split out in some live graphs.

Click the Edit icon to open the filtering options:

Use the GUI to alter Qscore and to define minimum and maximum readlength for a pass read, if required.

From here, you will see a progress bar below the flow cell to show the progression of the sequencing script.

In some cases, the device will take a few minutes before starting a sequencing run if an alignment reference file is used. A progress bar will show the progress before sequencing begins.

Flow cell health will be displayed after the first pore scan.

Below are recommended troubleshooting tips if there are unexpected differences in pore numbers:

• If there is a significant reduction in active pores in the first pore scan, restart MinKNOW.
• If the numbers are still significantly different, close down the host computer and reboot.
• When the numbers are similar to those reported at the end of the flow cell check, restart the experiment. There is no need to load any additional library after the restart.

This is only necessary if you want to stop your run before the end of the set run time.

Confirm to stop experiment by clicking:

• Stop sequencing which will start catch-up basecalling
• or Stop sequencing and basecalling which will stop both sequencing and basecalling immediately.

A run report containing information about the sequencing run and performance graphs can be generated manually by clicking Export run report and selecting which experiment to export to html.

Run reports are automatically generated for MinION Mk1B running on Linux. However, for MinION Mk1B running on Windows or Mac, the run reports need to be manually generated.

For more information about the run report, please see the Run report section of this document.

A pore activity .csv file is also generated for every run.

The report and .csv files are saved to the same folder as the .fast5 and .fastq read files e.g. :\data\experiment\sample_ID\ for MinION Mk1B.

Ensure the experiment name and sample ID does not contain any personally identifiable information.

Note: If sample ID is not filled in, there will be no sample ID in the folder structure.

This rule can be used to define a target amount of data to reach before a sequencing run is stopped. This can be specified for either estimated or basecalled bases and your data target will be available to view on the experiment graphs to allow you to monitor data progress.

Please note, basecalling must keep up with data output in real-time. If the device or basecall model will not keep up and reach the target output before the run limit rule is met, we recommend using the "Estimated bases" option. However, if your experiment will not reach the target data before the end of the experiment as defined by the run limit rule, you will be warned by the UI.

Use drop-down menu to select for "Estimated bases equal" or "Basecalled bases equal" and input the value in either Gb or Mb.

The output section provides variables for data output including file name, location and format.

Click the Edit icon to open the options.

Output settings:

Data saved as:

Check the name of the output file for the data.

Output location:

Confirm the location for the output data file. Click the file path name to open a pop-up to alter file path or create a new file.

Click Choose location on the pop-up to confirm new file location.

Output location storage capacity:
A bar indicator is displayed below the selected data output file location. This bar will display red when the disk space used reaches more than 80% of the total available disk space. Otherwise, the bar will display green. Below the bar, you can see how much drive space is available.

Basecalled output options:

Confirm output file type and file compression using the checkboxes.

Note: Below, reads per file can be changed for both raw reads and basecalled reads, but take note:

• Fewer reads per file: reads become more quickly available. However, too few reads per file means MinKNOW may not keep up with writing out files in real-time.
• More reads per file: reduces the number of files especially for amplicon/cDNA experiments that produce a large number of reads. Some downstream analysis tools may have an upper limit on the uploaded file size.

Basecalled output type:
Output file type can be selected between .FASTQ or .BAM files. The .FASTQ will be on as default if basecalling in real-time.

File output frequency can be adjusted for basecalled files based on two options:

For barcoding runs, basecalled reads are split into files by barcode by default.

Gzip compression of FASTQ files is on by default of basecalled reads. Note: FASTQ Gzip files may prevent some downstream informatics applications.

Raw reads output options:

Raw reads: Raw reads output can be saved as .POD5 or .FAST5.

• For Kit 14 chemistry and SQK-RNA004, .POD5 is the default file output. The .POD5 output generates files hourly.
• The .FAST5 output file is the default format for our previous and "legacy" chemistry kits. The.FAST5 output produces files for every 4000 reads.

.POD5 is a Nanopore-developed file format which stores Nanopore data in a more accessible way and can be used as an alternative to FAST5 output. This output also writes data faster, uses less compute and has smaller raw data file size.

We recommend keeping the default settings.

Raw reads split by barcode: Raw read files generated in the .POD5 format can now be split by barcode (if using one of our barcoding sequencing kits.
Please note, this feature is turned off by default and not available for .FAST5 files.

Filtering options can be used to determine which reads are classed into pass or fail files. These options may also be used to determine which predefined reads, read lengths and Qscore during basecalling can be split out in some live graphs.

Click the Edit icon to open the filtering options:

Use the GUI to alter Qscore and to define minimum and maximum readlength for a pass read, if required.

From here, you can see a progress bar below each flow cell to show progression of the sequencing script.

In some cases, the device will take a few minutes before starting a sequencing run if an alignment reference file is used. A progress bar will show the progress before sequencing begins.

Flow cell health will be displayed after the first channel scan.

Below are recommended troubleshooting tips if there are unexpected differences in pore numbers:

• If there is a significant reduction in active pores in the first pore scan, restart MinKNOW.
• If the numbers are still significantly different, close down the host computer and reboot.
• When the numbers are similar to those reported at the end of the flow cell check, restart the experiment. There is no need to load any additional library after the restart.

This is only necessary if you want to stop your run before the end of the set run time.

Confirm to stop experiment by clicking:

• Stop sequencing which will start catch-up basecalling
• or Stop sequencing and basecalling which will stop both sequencing and basecalling immediately.

A run report containing information about the sequencing run and performance graphs are automatically generated but can be generated manually by clicking Export run report and selecting which experiment to export to html.

For more information about the run report, please see the Run report section of this document.

A pore activity .csv file is also generated for every run.

The report and .csv files are saved to the same folder as the .fast5 and .fastq read files e.g. :\data\experiment\sample_ID\ for MinION Mk1B.

Select Continue to move to the Kit Selection page.

Ensure the experiment name and sample ID does not contain any personally identifiable information.

To use previously saved settings, please see the "Save sequencing run settings" page of this protocol.

Use "Select all available" to select all the connected flow cells or use the diagram above to select specific flow cells for an experiment.

Note: If sample ID is not filled in, there will be no sample ID in the folder structure.

One sequencing kit can be selected as well as one or more expansions. If a sequencing kit does not have any associated expansions, no expansion options will appear.

The filter options may be used to find the kit used. For example, click DNA to filter for DNA sequencing kits.

For control runs, there is a Control checkbox which only filters for the control experiments of the kits. This will automatically set the sequencing parameters for a control run. Note: Run length will be reduced to 6 hours for control experiments.

Click Continue to navigate to the run configuration page.

At the top of the run configuration page you will see an overview of your experiment set-up and identifiers inlcuding:

• Experiment name: defined by user.
• Positions: Flow cell position(s) being used in the sequencing experiment, and the associated sample IDs for the position(s).
  Note: If using multiple flow cells, click "show details" to open a window displaying all the positions used and the associated sample IDs.
• Flow cell type: automatically detected by the MinKNOW software.
• Sequencing kit: the sequencing kit used for DNA/RNA library preparation, user-defined.

The basecalling option is on by default to perform real-time basecalling. This can be switched off and basecalling performed post-sequencing.

Note: If basecalling is disabled, barcoding and alignment will not be performed during sequencing.

Modified bases is off by default. This can be switched on to use the CpG context models and basecall 5mC and 5hmC.

To specify your basecall model and modified bases, click the Edit icon to open basecalling options dialogue box.

Barcoding options are only available when a barcoding sequencing kit or expansion has been selected. Barcoding can be switched off and performed post-sequencing.

To specify the barcoding options, click the Edit icon to open the barcoding options dialogue box. From here, barcode trimming and custom barcode selection can be defined.

By default, barcoding trimming is off. This can be enabled to remove barcodes from demultiplexed reads. Please note, some primer sequences may also be trimmed together with the barcodes.

By default, custom barcode selection is off. This can be enabled to only select for specified barcodes used in your library preparation for the current sequencing run.

Note: Specifying barcodes must be entered as:

• Individual numbers.
• Numbers separated by commas.
• Range of numbers separated by a dash.
• A combination of numbers and ranges, separated by commas.

Some sequencing kits place barcodes on both ends of the read. By default, the barcode both ends feature is off. If this feature is enabled, the barcode will only classified if a barcode above the minimum barcode score is present at both ends of the basecalled read.

Note: For barcoding to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

To use alignment during sequencing, upload an alignment reference file as a .fasta or .mmi file. We recommend uploading a reference locally on bacterial-sized genomes. Uploading a file can take a few minutes and is compute-dependent.

A reference file can contain multiple entries in the same file (e.g. multiple chromosomes) and alignment hits from these files are used to populate the alignment graphs which can be viewed on the GUI.

A BED file can also be uploaded alongside the reference when there is a specific interest in a particular region of the reference (e.g. specific gene in a chromosome). Alignment hits from BED files will be highlighted in the sequencing .txt file generated in the data folder. Click Edit options to open a dialogue box to upload a BED file.

Note: For alignment to be performed during sequencing, basecalling must be enabled.

By default, alignment is turned off.

Enabling adaptive sampling will allow you to enrich or deplete specific sequences from your aligned seuqencing data.
For our barcoding kits, the barcode balancing feature is also available using adaptive sampling through the "beta" features in MinKNOW.

More information on this feature can be found in our adaptive sampling documentation.

This feature allows you to set up the rules to define when a sequencing run will stop. If multiple rules are set up, the first rule met will stop the run.

Click the Edit icon to open the options.

Run limit

This rule must be defined based on run time length in hours or when a flow cell is end of life and has no more sequencing pores available.

Use the drop-down menu to choose:

Una indicación de que no se están realizando experimentos es la ausencia de barras de estado debajo de las celdas de flujo.

An indication no experiments are running is the lack of an experiment status bar beneath individual flow cells.

Select whether you want to process reads in sub-directories.

If your chosen read input folder contains sub-directories with FAST5 files, you can choose whether to basecall files in these sub-directories by enabling this option.

By default, MinKNOW will create a /basecalled folder in /data. You can set a different folder in which to save the basecalled reads. Note: This must be a sub-folder of /data directory.

By default, output FASTQ files will be compressed using Gzip. This feature can be toggled off by the user.

Set-up the configuration of your basecalling run using the drop-down menus:

• In the run setting, select the parameters used to initially sequence the data.
• In the basecalling settings, select the basecall model used to process raw signal, and whether to use modified basecalling.

Once all the parameters have been selected, the basecalling configuration will be displayed in the lower panel.

Given the recent improvements to basecalling accuracy, Q-score cut-off for reads put into the "pass" folder has been increased to:

Fast basecalling model >8 High accuracy (HAC) model >9 Super accurate (SUP) model >10

Select whether you want to process FASTQ reads in sub-directories.

If your chosen read input folder contains sub-directories with FASTQ files, you can choose whether to barcode FASTQ files in these sub-directories by switching this option on.

Note: Data can only be saved to the /data folder.

By default, MinKNOW will create a /barcoding folder in /data/. You can set a different folder which to save the barcoded reads. Note: This must be a sub-folder of /data directory.

You can also select your output file formats to be generated as .BAM or .FASTQ.

MinKNOW will write out basecalled reads into barcode-specific folders and enable demultiplexing during basecalling.

Users are able to choose specific settings, including trimming barcodes and barcoding both ends (available for specific barcoding kits).

Select whether you want to process FASTQ reads in sub-directories.

If your chosen read input folder contains sub-directories with FASTQ files, you can choose whether or not to align FASTQ files in these sub-directories by switching this option on.

Note: Data can only be saved to the /data folder.

By default, MinKNOW will create an /alignment/ folder in /data/. You can set a different folder which to save the aligned reads. Note: This must be a sub-folder of /data directory.

The alignment reference must either be a FASTA file.

However, there is also the option to use a BED file alignment reference as well.
