Hi Pascal,
As a follow up, I have checked the troublesome 2OIU.py.pdb on a Ubuntu Linux (64-bit) machine, and was able to reproduce the bug. Interesting, the issue did not show up with the original PDB entry
2oiu; otherwise, I've have caught it
. As noted in my previous reply, this bug did not show up on Mac OS X either. So in the future bug report, please remember to give sufficient details.
Anyway, thanks for using DSSR under 'extreme' conditions, which certainly helps to make the program more robust. In DSSR v1.0.1-2014jan31, this bug has been fixed, among a few other improvements. Have a try, and report back if you have further issues.
Best regards,
Xiang-Jun
