classify error : ZeroDivisionError: division by zero

[michoug]

Hi,
When running the following command

enrichm classify --genome_and_annotation_matrix ko_frequency_table.tsv --aggregate --output Classify

I got this error

ZeroDivisionError: division by zero

It doesn't appear if I add the option --cutoff 0.5

Hi there,

Thanks for the bug report. This just looks like a straight up bug. I'll take a look at this asap

Thanks,
