mv: cannot stat

If using a compressed (gzip'ed) input fasta with DAS_tool v1.1.2, the following error occurs:

Running DAS Tool using 12 threads.
predicting genes using Prodigal V2.6.3: February, 2016
identifying single copy genes using diamond version 2.0.5
mv: cannot stat 'tests/output_amy_n8_graphbin/bin_refine/7_T6/DAS_Tool/bins_proteins.faa.scg': No such file or directory

rm: cannot remove 'tests/output_amy_n8_graphbin/bin_refine/7_T6/DAS_Tool/bins_proteins.faa.all.b6': No such file or directory
single copy gene prediction using diamond failed. Aborting

If I uncompress the fasta first, then das_tool completes successfully. If das_tool cannot use gzip'ed files as input, then it would help to have a better error than the mv: cannot stat errors shown above.

It appears that the mv error is due to no diamond hits:
