Dear Chimera users I have been trying to select the atoms involved in the interface of a receptor/ligand complex in ChimeraX without success. In UCSF Chimera e.g. open 4RSC del solvent sel #0:.b del sel select ligand zr>10 del sel focus measure buriedArea protein ligand sel @/buriedSASArea “Only atoms at the interface are selected” = OK **The interface buried area calculation was performed and the atoms involved in the buried area were selected. However, I wish to do the same in ChimeraX, for surface area calculations: e.g. open 4RSC del solvent del /B select ::name="A3V" view sel measure buriedarea protein withAtoms2 ligand sel t list t cutoff 0 “All atoms in the interface are selected per residue” = KO The results of the calculations are the following: UCSF Chimera = 719.643 ChimeraX = 719.65 = OK I have difficulties to select only the atoms in the interface, not all atoms of the residues, I have tried several ways to do this but it has been complicated, I even tried to insert the command “sel @/buriedSASArea” of UCSF Chimera in ChimeraX without success. Sincerely.
