Groovy Map containing sample information e.g. |
|---|---|
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)' |

| 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 |
