Hi Teo,
Thanks for the quick reply. I was looking mostly at regtest-4. Any
indication as to when the projected version may become available?  I
have done some metadynamics runs already and I wanted to optimize a 1D
path based on the 2D FES. The other option would be to use trace_irc
on the FES and then do umbrella sampling (as suggested by Bernd Ensing
et al.) but it would be much better to have a more rigorous definition
of the path.
