Hi Francesco, Well, it's not really a trick, you can just use the "serialNumber" attribute like other attributes in the command line, for example: select @/serialNumber=19 sel @/serialNumber>12 and serialNumber<16 see "atom specification" <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html> especially the section on attributes <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#descrip...> and atom attributes list <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#atprops> Elaine ----- Elaine C.

Hello: Is any trick to select by atom number? Having NAMD files with CHARMM FF, i.e., SEGID and no chain ID, I find now difficult to use CHIMERA the way I used it.
