Hi Sabine,
The other option if TclBC is too cumbersome or slow is to go in and
hard code something into NAMD. Search for GlobalMasterMisc in the
source for an example. I haven't looked at the new namd 2.7 source to
see if this is still and available option or if there is a cleaner
way, but this was a decent solution that I used with 2.6.
