Process
Name JELLYFISH_COUNT
Input 3 channels
#1 tuple
meta map

Groovy Map containing sample information e.g. [ id:'sample1' ]

fasta file

Nucleotide sequences in FASTA format

*.{fasta,fa,fna,faa}
kmer_length integer

k-mer size to use

size string

Specifies the memory hash size (in bytes) to allocate for the k-mer counting hash table (e.g., '100M'). A mean estimation could be carried with this formula: 'genome size + (genome size * coverage * kmer-length * error rate)'

Output 2 channels
#1 jf tuple
meta map

Groovy Map containing sample information e.g. [ id:'sample1' ]

${prefix}.jf file

Jellyfish binary k-mer database

Tool Description Homepage
jellyfish Jellyfish is a tool for fast, memory-efficient counting of k-mers in DNA. A k-mer is a substring of length k, and counting the occurrences of all such substrings is a central step in many analyses of DNA sequence https://github.com/gmarcais/Jellyfish
