segment-cnv and plot-cnv issue

[BERICP01]

Hello!
I am facing two problems while running neoloopfinder

1. when I run segment-cnv I continue to get this error with most of my cool matrix at different resolutions:

ARGUMENT LIST:
CNV Profile = /gpfs/data/HernandoLab/home/bericp01/HiC/results/CNV/501mel_sgCHD7-2_NeoLoopFinder/501mel_sgCHD7-2_25k.CNV-profile.bedGraph

2. all my plots are not centered to the 0 but rather always below zero irrespective if are cancer or normal cells. Any clue?
   

Any help will be really appreciate!!!
Thanks
