Filter that disallows hybridization changes

Open hannahbaumann opened this issue 4 months ago • 1 comments

In some mappings in ligands in the PLB system, mapping atoms that are connected by single or double bonds can lead to problems. It would be great to see if mappings that do not map these hybridization changes would perform better.

Example 1: P38 Edge lig_p38a_2gg - lig_p38a_2ee download

Hi @hannahbaumann , do you think this filter could help you out? https://github.com/OpenFreeEnergy/kartograf/blob/8ef8f8850ed1bbf0afcf656bc80172bd305f5f91/src/kartograf/filters/element_change.py#L54
