I used jellyfish to counting kmers and my input files were zipped fastq. I used the commond :
jellyfish count -m 17 -o 17mer_counts -s 500000000 -t 5 -c 3 read_1.fq.gz read_2.fq.gz
And I got the errors like this:
terminate called after throwing an instance of 'std::runtime_error' what(): Unsupported format
I don't know how to solve it.
