Hi Susan, Unfortunately it’s not as friendly as Chimera (yet). You would need to force recomputing the surface at each trajectory frame, for example with commands like the following for morph trajectory model #3: alias stuff surf close; surf #3 & protein perframe stuff; coordset #3 1,21; wait 21; ~perframe In that example I first create an alias “stuff” (could be some other word) that includes all the actions I want to do at each frame, then define it as a per-frame action to occur at each step of trajectory playback with the “coordset” command. The “wait” is required so that stopping the perframe action with “~perframe” won’t happen until after all the trajectory frames are played. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/perframe.html> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/coordset.html> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/wait.html> Closing the surface is also required because otherwise “surface” thinks it doesn’t need to do anything because a surface for the same set of atoms is already there… it isn’t smart enough (yet) to realize that the atoms may have moved around.

How can I generate a morph with a molecular surface representation?
many thanks Susan
