Hello all!
I am trying to run a simulation imposing harmonic constraints to the center
of mass of some atoms in 18 protein molecules in NAMD, all of them are in
the same pdb file. I am following the user-defined forces in NAMD tutorial
and actually I already ran a simulation using the tcl forces script from the
tutorial but I would like to know if I could slowly take off this forces
from my system, if this is possible, What command should I change from the
original tcl forces script?
Thanks for your attention and your possible help.
