Hi Helen, This specifier: :241.water should select just water 241. Another trick you can use is to type a '+' in the command (separated by spaces from the rest of the command) and then control-click on an atom in the residue you want. The '+' will be replaced by the specifier for that atom, in your case probably something like: :241.water@O You would then just delete the "@O" part. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Mar 31, 2008, at 10:14 AM, hjoseph@brandeis.edu wrote:
Hi Everyone, I want to select one water molecule but every time I try to do that, all the molecules get selected. Could some one tell me the command line instruction for selecting water 241.
Thanks, Helen Josephine
