TMAP: exception src/io/tmap_file.c

[leukogenom]

TMAP can't seem to open any reference files that I pass it. I've tried several different reference files but I always get the following exception

src/io/tmap_file.c:83: in function "tmap_file_fopen"
./<filename>.fasta.fasta.tmap.anno
fatal error: could not open the file
the file stream error was: No such file or directory

I'm not sure why tmap_file_fopen is trying to open a file that is named
<filename.fasta.fasta.tmap.anno>

Did you try indexing the FASTA first with "tmap index -vf <in.fasta>"?

Thank you Nils. That did the trick
