ok, so I am trying to write a colvar config file (please see the attached),
and I also add these two lines to the main NAMD confg file:
colvars on
colvarsConfig rmsd
But when I run this, it gives me this error:
But NAMD crashes and exits, with this error message:
colvars: Error: no collective variables defined.
colvars: If this error message is unclear, try recompiling with
-DCOLVARS_DEBUG.
FATAL ERROR: Error in the collective variables module: exiting.
I don't understand why it doesn't recognize the colvar that I have declared?
Any idea?
thanks
