Hi Yasser, Not sure whether you want to select the atom only in one specific model, or in all of them at the same time, so I'll answer both questions. To select all of them, command: select :561@oe1 To select in just one model, include the model number. For example, if the file is opened as 0, the models in it are 0.1, 0.2, 0.3 ... so your command would be something like select #0.1:561@oe1 These are examples of "hierarchical" atom selections, described here: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#hierarc...> I hope this helps, Elaine ---------- Elaine C.

How can i select the 1 OE1 GLU atom in each the model? Any hint...
Thanks... ;)
