[Chimera-users] Rotating about an axis

[Thomas Goddard]

Hi Kevin,

   The command "turn x 23" will rotate active models about the screen x 
axis by 23 degrees.  The command "turn 1,1,0 180 center 0,2.5,2.5 coord 
#1 models #1" rotates just model #1 by 180 degrees about axis 1,1,0 
defined in the local coordinates of model #1 about center point 
0,2.5,2.5 also in model #1 local coordinates.  The fancier forms of the 
turn command are only in Chimera 1.4 daily builds.

   You align multiple structures by aligning them all to one reference 
structure.  You can align specific residues with the "match" command:

Do do a sequence based structure alignment look at the MatchMaker tool 
or command:

Best to send questions to chimera-users at cgl.ucsf.edu.
