[Chimera-users] independent movement

[Elaine Meng]

Hi Michel,
namesel is a newer command added after version 1.2304 - get the  
recent snapshot to use this command:
http://www.cgl.ucsf.edu/chimera/download.html#snapshots

The release notes for this snapshot list what has changed since 1.2304:
http://www.cgl.ucsf.edu/chimera/1.2349/docs/relnotes/snapshot.html

The links I included in previous messages were to "development"  
documentation, which will always be newer than what you have  
(although mostly the same if you have a recent version).  The  
documentation included with a download is more synchronized - you can  
access and search your local copy of the documentation using the  
Chimera Help menu.
