Hi Stefano, VMD has an interface for the Colvars module:
If you have a metadynamics simulation already run with NAMD, you could load
its state file using the "cv" command, and loop over trajectory frames
while calculating the energy of the metadynamics potential. At that point,
you can use "animate goto" to display the frame with a certain free energy.
It is a relatively recent feature for VMD, try if possible to use a very
recent version, preferably compiling the CVS version of VMD:
and using the latest colvars version:
Or simply wait for VMD 1.9.3 to be out.
