Hi Giacomo,
Sorry for the hassle; just one more question on this particular ABF
calculation.
If I want to study the conformational transition A --> B and use
the structure of B as a reference for the RMSD colvar, is the ABF bias
going to "drive" the RMSD of A with respect to B from the upperboundary
value (that I will calculate by superimposing A and B) to the
lowerboundary
value (a small one, like 0.1)?

I would really appreciate any tips on this
