Workflow for sequencing with ONT Nanopore, from basecalling to assembly.
- Guppy (basecalling of raw reads)
- MinIONQC (quality check)
- FASTQ merging from multi into one file
- Kraken2 (taxonomic classification)
- Krona (classification visualization)
- Flye (de novo assembly)
- Medaka (assembly polishing)
- QUAST (assembly quality reports)
