Hello Chimera experts, Here is another movie making question. I noticed that disp and ~disp trigger frames to be recorded, without a call to wait. For example: disp #2 movie crossfade 25 ~disp #2 disp #3 This would produce a movie that crossfades from model #2 to blank, with #3 suddenly appearing. To get crossfades between two ligands, I had to use: disp #2 movie crossfade 25 perframe "~disp #2" frames 1 disp #3 movie crossfade 25 Based on the documentation I wasn't sure if this was intended behavior or a bug. Did I miss a more elegant way to crossfade between two models? Thanks, -da
Hi Daniel, Yes there is a frame drawn between each command that is on a separate line in the Chimera command file. So the crossfade you want should use commands disp #2 movie crossfade 25 ~disp #2 ; disp #3 where the display of model #3 is done on the same line, separated by a colon, after the crossfade command. You can put as many commands on a line as you want separated by semicolons. These behaviors are documented although there is so much Chimera documentation it may be hard to find. Tom

Thanks, Tom! Now, I understand why wait and crossfade work the way they do as well. I'll take a deeper dive into the docs and try and find it. Best, -da On Tue, Dec 20, 2016 at 1:59 PM, Tom Goddard <goddard@sonic.net> wrote:

Hi Daniel, The general command-file description mentions the implicit “wait" at end-of-line, and combining commands with semicolons: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/indexcommand.html#cmdfile> Best, Elaine ----- Elaine C.
