Hi Fengwei, There is a "vop zone" command in Chimera similar to "volume zone" in ChimeraX. Same function, but the keywords and syntax are different, see <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#zone> E.g. something like: vop zone #2 #0:.a 2 As for your other question, Chimera has a "precessionTilt" option to the "roll" command, but ChimeraX does not have this option currently. Looking at this kind of motion makes me feel seasick, so I don't use it in my own work. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/roll.html> I hope this helps, Elaine ----- Elaine C.

Dear Developer, I am wodering if there is a command of Chimera can achieve the same function like "volume zone" in ChimeraX? I tried the command "vol zone #2 near #0:.a range 2", but the chimera always said "unknow keyword #2"~ Another thing is that I wonder if there is a command of ChimeraX can achieve the same function like "turn z 2 360 precess 20" in Chimera (to achieve the Wobble motion / "wiggle-rock" motion, like nutation in pymol)~ The I tried 1.14, 1.15 and the latest daily built versions of Chimera. The ChimeraX version I used is 1.0, Many thanks! Best, Fengwei
