NAME

       kmc - count kmers in genomic sequences

DESCRIPTION

       KMC—K-mer  Counter  is  a utility designed for counting k-mers (sequences of consecutive k
       symbols) in a set of reads from genome sequencing projects.

SYNOPSIS

       kmc [options] <input_file_name> <output_file_name> <working_directory>

       kmc [options] <@input_file_names> <output_file_name> <working_directory>

OPTIONS

       -v - verbose mode (shows all parameter settings); default: false

       -k<len> - k-mer length (k from 1 to 256; default: 25)

       -m<size> - max amount of RAM in GB (from 1 to 1024); default: 12

       -sm - use strict memory mode (memory limit from -m<n> switch will not be exceeded)

       -p<par> - signature length (5, 6, 7, 8); default: 7

       -f<a/q/m> - input in FASTA format (-fa), FASTQ format (-fq) or mulit FASTA (-fm); default:
              FASTQ

       -q[value]  -  use  Quake's  compatible  counting  with [value] representing lowest quality
              (default: 33)

       -ci<value> - exclude k-mers occurring less than <value> times (default: 2)

       -cs<value> - maximal value of a counter (default: 255)

       -cx<value> - exclude k-mers occurring more of than <value> times (default: 1e9)

       -b - turn off transformation of k-mers into canonical form

       -r - turn on RAM-only mode

       -n<value> - number of bins

       -t<value> - total number of threads (default: no. of CPU cores)

       -sf<value> - number of FASTQ reading threads

       -sp<value> - number of splitting threads

       -sr<value> - number of sorter threads

       -so<value> - number of threads per single sorter

EXAMPLES

       kmc -k27 -m24 NA19238.fastq NA.res \data\kmc_tmp_dir\

       kmc -k27 -q -m24 @files.lst NA.res \data\kmc_tmp_dir\
