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
