Hey you vmd scripting wizards, forgive me if this has been asked (and
answered) before. I looked through the archive and saw your script for
counting hydrogen bonds ("hbonds time series"), but I have something even
easier (I think) that I'd like to do: count atoms/residues/etc that qualify
for a given selection. For example, if I ask for say "resname SOD within 7
of nucleic" the script would return a number. This could then be started in
tandem with "selection_update". When you "play" the trajectory, you'd then
get a selection time series.

Thanks in advance for your help.
