Error when search for Hbonds

[IsmaheneMesbah]

Hi,

I want to perform H bonds analysis, I am following the tutorial:

hbonds = pt.search_hbonds(pdb_file) hbonds.values

I have the following error:

`Traceback (most recent call last):

File "/Users/macbookair/smd_software/readGromacs.py", line 109, in hbonds = pt.search_hbonds(pdb_file)
