Uninformative crash with low read depth samples

From Aatzli Coria:

Here is the command I entered:
python /data/data2/Programs/RingMapper-master/pairmapper.py --modified_parsed Pipeline_Modified_XXXX_parsed.mut --untreated_parsed Pipeline_Untreated_XXXX_parsed.mut --profile Pipeline_XXXX_profile.txt --out XXXX

Here is the error I got:
python /data/data2/Programs/RingMapper-master/pairmapper.py --modified_parsed Pipeline_Modified_XXXX_parsed.mut --untreated_parsed Pipeline_Untreated_XXXX_parsed.mut --profile Pipeline_XXXX_profile.txt --out XXXX
