Dear Huy, When you report a problem, it is helpful to say what version of Chimera you are using. Probably you are looking at documentation that is newer than your version of Chimera. The roll command in your e-mail works fine in recent daily builds (Chimera version 1.4) but not the production release (1.3), because the syntax has changed. You can get a new daily build here: <http://www.cgl.ucsf.edu/chimera/alpha-downloads.html Instead of going on the Web for Chimera documentation, you could just use the documentation included with your Chimera download (use the Help menu to access or search it, or the "help" command, for example "help roll"). That way you won't get confused by documentation from different versions of Chimera. Here is a list of what changed since the production release: <http://www.cgl.ucsf.edu/chimera/docs/relnotes/snapshot.html> Best, Elaine ----- Elaine C.

Dear all,
I tried the roll command with my model (EM map) open:
roll z 30 1 center 50,50,50
Chimera showed msg "wait_frames argument not implemented".
Just wonder how to implement that command without the error?
