man kmc_tools-union (1): calculate union of two KMC databases

SYNOPSIS

kmc_tools union <input1 [input1_params]> <input2 [input2_params]> <output [output_params]>

DESCRIPTION

The output database will contain all k-mers present in both input sets. For the same k-mers in the first and the second input, the counter in the output is equal to the sum from both inputs.

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
