Elaine and Eric, Thanks. Works great. I don't see the menu options but that's okay as I'm fairly comfortable with the command line anyway. P.S. don't get the reply-to header comment.

How would I label all atoms in a structure without labeling hydrogen atoms? I'm trying to label a small molecule with about 60 non-hydrogen atoms.
