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.

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
