Hi Brandon, Use two range options on the perframe command perframe “something $1 ; anotherthing $2” range 0,199 range 1,200 and use $1 and $2 to substitute in the two values for the two ranges. Tom

I am attempting to use the measure convexity on each frame, and seem to have a mismatch between the frame number which goes from [0 - (N-1)] and the volume child which goes from [1 - N]. Is there a way to augment the $1 value to be $1+1?

Attached are the command calls. This displays the convexity properly on the called frame: vseries play #1 jumpTo 1; measure convexity #1.2 smoothingIterations 12 palette cyan-gray-maroon range -1,1;

The does not display it because of the mismatch: movie record; perframe "vseries play #1 jumpTo $1; measure convexity #1.$1 smoothingIterations 12 palette cyan-gray-maroon range -1,1;" range 1,200; wait 200; movie encode C:\Users\LLSM\Desktop\Convexity.mp4 quality highest framerate 25

Thanks in advance. -Brandon ____________________ Brandon Scott, PhD SDSMT, Nanoscience _______________________________________________ ChimeraX-users mailing list ChimeraX-users@cgl.ucsf.edu <mailto:ChimeraX-users@cgl.ucsf.edu> Manage subscription: http://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users <http://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users>
