ValueError: negative dimensions are not allowed when processing proton

[jproman]

Hi all

I am having issues at processing proton resonance files. Apparently, when it is trying to find the baseline signal, it ends up having an array with negative dimensions.

Traceback (most recent call last):

ValueError: negative dimensions are not allowed

Any idea what is going on?

Thank you very much
