Allow numbers as chainIDs/segIDs

[mtrellet]

When a PDB has numbers instead of characters as chainIDs and/or segIDs, calc_fcc_matrix returns the following error:

1 + BEGIN: Mon Nov 13 01:18:23 2017
2 + Parsing 202 contact files
3 Traceback (most recent call last):
4   File "/home/enmr/services-enmr/HADDOCK2.2/server/run/userrun002472/run1/tools/calc_fcc_matrix.py", line 142, in ?
5     c = parse_contact_file(args, exclude_chains)
6   File "/home/enmr/services-enmr/HADDOCK2.2/server/run/userrun002472/run1/tools/calc_fcc_matrix.py", line 26, in parse_contact_file
7     contacts = [ set([ int(l) for l in open(f)]) for f in f_list if f.strip()]
8 ValueError: invalid literal for int(): 10087-1510438-14

This is due to a wrong output of the contacts by make_contacts:

10242-1510309-14
10242-1510310-14
10244-1510308-14

Switching back to alphabetical characters in the PDB solves the problem. However, numbers are allowed in the official PDB format.

Still have this problem.

• BEGIN: Wed Mar 27 09:54:38 2019
• Ignoring chains. Expect a considerable slowdown!!

Hi @LilySnow @amjjbonvin

Back to work, trying to figure this out. Could you provide me with an example PDB file to reproduce this issue? Please paste it as a gist (https://gist.github.com) instead of pasting it here.

This seems to work properly here on my laptop. Did you update the code to the latest version?
