[Chimera-users] Morph colors

[Tom Goddard]

Hi Rajan,

  Yes, you would have to measure the center for each frame and use that for the zone coloring.  In order to perform a command or sequence of commands each frame you use the “perframe” command.

Elaine Meng said she tried it and did not get your case to work though, so there may be some unexpected difficulties.  But you should try it.

	Tom
