cLoops2 montage error

[YuZhang337]

Hi Yaqiang @YaqiangCao,
Sorry to bother you again. I tried using the cLoops2 montage command to show the interaction between some enhancers. These enhancers are all included in the loop file.My command line is as follows： cLoops2 montage -f ../HiC-540-samp/chr2-chr2.ixy -bed test.bed -o HiC540-samp-chr2-top -simple -p 20. But got the following error:
Traceback (most recent call last):

I tried expanding the enhancer peak region, but I still got the same error.Is there anything I need to pay special attention to in this bed file?I look forward to your reply.
