For example, Tyr 66 have two side chain conformations, however using the command below, it only showed one conformation. resfit /a:66 map #1 (a very nice command, by the way) I then used Chimera 1.15 to view the PDB coordinate, and it showed two side chain conformations for Tyr66 (as I saw in PyMol); on the other hand, Chimera X only shows a single conformation. Is there any way to display the two alternative conformations using Chimera X? Thanks a lot for your time, and possible help! Best wishes, Winston " enhancement assigned moderate Volume Data all ChimeraX
