dsk readme shows command line with -file and -kmer-size.

The one I used (no --version, so don't know which) on genouest.org cluster doesn't understand those options.
It seems to be only dsk file_in kmer_size.

So time for you to update the readme or for me to update dsk ?
Sebastien, 

You need to update your DSK version.
