Error while calling TEs from pooled samples

Closed this issue · 4 comments

I was trying to apply RetroSeq call to a dataset consisting of two discover-out files and their corresponding BAM-files. The programs starts to run, but then the following errors appears and I get an empty VCF file.

I'd very much appreciate any workaround or fix to circumvent this problem.
Thanks,

Fritjof

Hi Fritjof - could you post the first couple of lines from the out_files.fofn file? And if this is a fofn, could you post the first couple of lines from each of the fofns?

Hi,
It's a fofn and each files looks like this:

out_files.fofn:

Those files look fine. I can't see any obvious reason why this should be happening. I've just made a commit on the master to print out the offending line causing the error. Could you download the master zip and run the calling phase? It should die with an error and print the line causing the problem.

Hi Thomas, thanks! Now it is the following. Apparently the fofn is not recognized correctly and is parsed as if it was the outfile itself. I switched to using the file prefix and then it worked.
