Multiprocessing error with .cool file #18
Description
Hello,
I am trying to run the tool with the following command:
python diffdomains.py dvsd multiple /data/T1_10000.cool /data/T2_10000.cool /data/TADS_DM.bed --reso 10000
But after appearing to run fine for a while it throws the following error:
...
chr9:75210000:75430000
chr9:106940000:107100000

The above exception was the direct cause of the following exception:
Traceback (most recent call last):

Any help will be highly appreciated!
Thanks :)
