KMC yields an error on fixed width fasta files

[mesti90]

I tried to run kmc (version 3.2.2) on fasta files downloaded from the NCBI ftp server.
The program gave only the following error message:
Error: unknown exception

After many hours I tried to change the fasta file from fixed width to one-line sequence format, and kmc finally worked.
Please add (1) a meaningful error message (2) support for fixed width fasta files

Hi,
thank you.
The error message should definitely be more informative. I think I have a fix for this, but this is not in the public version yet.
fixed-width fasta (or multif-asta) is handled in kmc with -fm switch. I guess you were using -fa. If no, please let me know what was your input file and the exact command line to run KMC.
Thanks again for reporting this and using KMC!

@marekkokot Thank you for your quick answer. I used the -fa switch, thanks for the info.

Great, thanks. I will keep this issue opened until I fix the error message.

I also encountered this problem and after using -fm it's cool to get the right result
