Re: Specifying Values for Rotating Constraints

I think it just rotates the existing harmonic restraint reference
coordinates. According to
"If there are atoms that have to be constrained, but not moved, this
implementation is not suitable, because it will move all reference
positions. Only one of the moving and rotating constraints can be used
at a time."

With the harmonic constraints I specify a force file and a column in the .pdb file for the force value. There is not an option like this for the rotating constraints. Where does NAMD read the force values for rotating constraints? If it is the initial coordinate file specified, should the column specified for harmonic constraints also be used for rotation?
