= kmc_tools-counters_subtract(1)
== NAME
kmc_tools-counters_subtract - calculate counters subtraction of two KMC databases
== SYNOPSIS
*kmc_tools counters_subtract* <input1 [input1_params]> <input2 [input2_params]> <output [output_params]>
== DESCRIPTION
The output database will contain only k-mers that are present in the first input set and have counters higher than the appropriate k-mers in the second set. For each k-mer the counter is equal to the difference between the counter in the first set and the counter in the second 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
== EXAMPLE
