[Open Babel] Doubts regarding random rotor search!!

2014-02-17 Thread anna
Dear all, I need to calculate electrostatic potential (ESP) derived atomic charges. I did geometry optimization with MMFF94s force field. Is it also important to do rotor search in order to minimize the molecule? Another question that I have is if rotor search should be done before or after

[Open Babel] fingerprinting

2014-02-17 Thread Kayleigh Ougham
Hi, I'm trying to generate some fingerprints for some drug molecules and everytime I try to run the commands listed on your wiki/tutorial site it just tells me it cant open the file? Please can you advise, the version I've got is 2.2.3 is the command different for this version? Thanks, Kayleigh

This is actually a pretty bad thing. But it may not be that easy to fix, and would result in a major change to the SMILES that OpenBabel produces (very unfortunate, as it requires large databases to be completely re-canonicalized). As far as I can tell, the code is still there.. As far as

Hi, I found the examples in the bug report. The code in canon.h handles disconnected fragments correctly. However, in smilesformat.cpp the symmetry classes are computed for the molecule as a whole. This is not what the canonical coding algorithm expects and the resulting smiles may be different
