Attribute error

Hello,

I am trying to get a structure using 3.1 version of ccpnmr. However, while trying to select preferences for setting xplor nih and talos n directory it shows an attribute error. This happens only on Linux and not on my windows version.

The error says
‘AttrDist’ object has no attribute ‘negativePeakPick1D’

Kindly let me know how to resolve this. Thank you.
