The output database will contains only k-mers that are present in the first input set but absent in the second one. The counter value is equal to the value from the first input set.

OPTIONS

For each input there are additional parameters:

-ci<value>

exclude k-mers occurring less than <value> times

-cx<value>

exclude k-mers occurring more of than <value> times

For output there are additional parameters:

-ci<value>

exclude k-mers occurring less than <value> times

-cx<value>

exclude k-mers occurring more of than <value> times

-cs<value>

maximal value of a counter

kmc -k28 file1.fastq kmers1 tmp
