step 11: ValueError: need more than 1 value to unpack

[NA1919]

hello,

I am running panX with branch associations. I have a metadata.tsv file and a descriptive metainfo.tsv file.
I keep getting this error on step 11:

/beegfs/work/workspace/ws/fr_na50-panx-0/pan-genome-analysis/scripts/sf_association.py:188: RuntimeWarning: divide by zero encountered in divide

thank you in advance for any help

I encountered this issue today as well, and was able to trace it back to the meta_config.tsv file, which had one or two empty lines at the end. Upon removing these, the script ran through completely without errors. Hope this still helps someone attempting to get panX to run.
