Primary data analysis
MinKNOW carries out several core tasks including: data acquisition; real-time analysis and feedback; data streaming whilst providing device control including selecting the run parameters; sample identification and tracking and ensuring that the platform chemistry is performing correctly to run the samples and local basecalling.
Local basecalling offers the user experimental setups for sequencing without any local infrastructure or where a stable internet connection is not available. Other compute setups using local infrastructure and basecallers are available, if required, and are detailed here.
MinKNOW produces .fast5 files using the HDF5 format to store data; they include raw data and basecalled files. Where the user requires fastq files, these can be easily extracted for use in customised analysis pipelines.
Onward data analysis
Nanopore sequencing enables basecalling and onward data analysis to be performed in parallel as the experiment progresses. The length of time the sequencing continues for can be tailored by the user to the specific application, based on the accumulated data. This enables efficient workflows and even real-time selective sequencing.
Currently there are two choices for onward data analysis: real-time analytical workflows or customised analysis pipelines, created by the user from a growing number of community-developed data-analysis tools. Tools continue to be developed for standard analysis as well as looking to use the real-time aspect of nanopore sequencing to be able to carry out analyses such as real-time assembly.
Real-time analytical workflows
Oxford Nanopore provides analytical workflows to support researchers.
|What's In My Pot? (WIMP)||Real-time species identification of fungi, bacteria, viruses or archaea||Available now|
|16S||Using the 16S rRNA gene for real-time identification of bacteria and archaea at the genus level||Available now|
|ARMA (Antimicrobial resistance)||Real-time identification of markers of antibiotic resistance, integrated with CARD||Available now|
|Human Exome Mapper||Real-time exome analysis||Available now|
To customise your analysis, basecalled files (fastq) are easy to extract from the read data, to be taken forward into a variety of analysis tools developed by users of nanopore technology. These new tools are designed both to work with the long reads produced by nanopore sequencing, and to use real-time analysis wherever it is needed.
