Hello, Recently, I stumbled upon this open source tool: PLIP - Protein-Ligand Interaction Profiler Analyze and visualize non-covalent protein-ligand interactions in PDB files From the abstract: --- [...] detection and visualization of [...] seven interaction types (hydrogen bonds, hydrophobic contacts, pi-stacking, pi-cation interactions, salt bridges, water bridges and halogen bonds). --- Website: http://plip.biotec.tu-dresden.de Open-source code: https://github.com/ssalentin/plip Paper: https://academic.oup.com/nar/article-pdf/43/W1/W443/17435622/gkv315.pdf or https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4489249/ And, when I am inside chimera looking at a protein-ligand complex, it would be super nice if this tool could be launched from within chimera (as in a menu "Tools -> Surface/Binding Analysis -> PLIP analysis (visualize non-covalent interactions)"). Or, maybe it could be a toggable button inside of ViewDock. Best regards, Francois.
