ValueError: not enough values to unpack about deepvirfinder

Hi Alex,

Thanks for using DeepVirFinder.

To help me debug, could you print the input and output of line 212?

print(code)
out = zip(*pool.map(pred, range(0, len(code))))
print(out)

See what you get? Thanks.

Hi Jie,

Thanks for the quick reply. After playing around with it some more I actually figured it was due to the length filtering I was putting it. It was too high so none of the contigs were passing through.

Thanks again,
Alex

If you have a fasta with many small seqs at the end, dvf.py will throw this error. Basically if no sequences pass the size filter in the 100 sequence chunk at the end of the fasta file, the "code" variable will be empty, but pred will still get called. I added an if statement (line 209 in my version) that fixed the issue.

if len(code) >= 1:
           print("   processing line "+str(lineNum))
           pool = multiprocessing.Pool(core_num)
           head, score, pvalue = zip(*pool.map(pred, range(0, len(code))))
