I have been using panX tool for pan-genome analysis (My computer info: Ubuntu 16.04 LTS, 64 bit version). I followed the instructions mentioned in the manual and installed all the dependencies (mcl, mafft, fastree, raxml, DIAMOND, treetime). After that, I ran the test as mentioned in the tool manual and end up with the following error,

mv: cannot stat 'GC00000142_aa_aln.fa': No such file or directory
mv: cannot stat 'GC00000142_na_aln.fa': No such file or directory

As an alternative option this tool can be ran in miniconda environment (mentioned in the manual), therefore I have tried the same but end up with the identical error as mentioned above. Please help me to fix this issue.
