I already know a few programs/web severs; however, I'm looking to see if there's one in particular that's considered the "best" (i.e. most preferred) in terms of analyzing protein-ligand interactions. I've noticed that when analyzing different protein-ligand complexes on several of these programs/web servers (e.g. UCSF Chimera, Discovery Studio, Protein-Ligand Interaction Profiler, etc), I sometimes get different results; therefore, any guidance or assistance with this would be really appreciated. Thank you!
