This is the nested workflow of the "parent" nanopore workflow without the guppy basecalling step
Workflow for sequencing with ONT nanopore, from basecalling to assembly quality. Steps:
- Kraken2 (taxonomic classification of FASTQ reads)
- Krona (classification visualization)
- Flye (de novo assembly)
- Medaka (assembly polishing)
- QUAST (assembly quality reports)
