eg5 lig_CHEMBL1084935 (present twice): Decide which stereoisomer to use #3

Closed hannahbaumann closed 1 year ago

hannahbaumann commented 1 year ago

ligand lig_CHEMBL1084935 has a charged tertiary amine and therefore also a "stereocenter". Both "stereo isomers" are deposited . Both have the same name which makes it difficult to separate them from each other in e.g. a ligand network. Here the question I have is whether to always include both in the calculations, or whether it makes sense to run a transformation between them, figure out which is the more favorable one and only include that one in future benchmark studies.

Compared both isomers with the structures deposited in the PLB from Hahn et al as well as with the structures in the structures deposited by Schrodinger (https://github.com/schrodinger/public_binding_free_energy_benchmark/tree/main/fep_benchmark_inputs/structure_inputs/merck). Kept the same isomer as was used in the other two sets. commit f7cf58eba0d86fd5d7e98a96825b323f5911b0a6
