Hi Eduardo, We intend to add a command to name the selection, but this has not yet been done. In the meanwhile, the "alias" command might do what you need. For example, instead of first selecting command> select ions z<5 & :/kdHydrophobicity>1 & ~ :trp (residues within 5 Angstroms of ions, with Kyte-Doolittle hydrophobicity greater than 1, but not tryptophans) and then naming the selection, you could alias the expression and reuse it: command> alias mystuff ions z<5 & :/kdHydrophobicity>1 & ~ :trp command> col byatom mystuff command> repr stick mystuff (etc.) or even command> sel mystuff if you needed the atoms to be selected for some other purpose. Man page for "alias": http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/alias.html Man page for command-line specifications: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/ frameatom_spec.html I hope this helps, Elaine On Apr 6, 2006, at 2:15 PM, Eduardo Sanz Garcia wrote:

Hi everybody,

Is there any way to give a name to a selection from the command line? Same as: Select... Name Selection... but from the command line.

Thank you.
