Error "CompactedDBG::construct(): Could not create tmp directory. Abort."

[JPegorino]

Using unitig-caller 1.3.0 to count unitigs in a set of draft genome assemblies for GWAS, I'm unable to produce any output and get the error "Error "CompactedDBG::construct(): Could not create tmp directory. Abort." It might be I'm just not running it correctly but I thought I'd report the issue in case this is a bug.

Thanks in advance for any advice and here's a record of my exact command with some troubleshooting that may help to diagnose/reproduce:

Do you have write access to /tmp, and enough space on it? But I also think this: --refs <(cut -f2 Data_records/unitig_counter_infile.txt) won't work. You'd need to format the infile correctly first, then point refs at it.
