No: the ntr=1 restraints are on the difference between the Cartesian
(xyz) coordinates in the actual structure and those in whatever file you
assigned to the "-ref" flag when you invoked sander or pmemd.

It depends on whether the starting coordinates (given by the "-c" flag)
are the same as or different from the reference coordinates (given by the
"ref" flag.) Setting ntr=1 sets up a bias towards moving the starting
coordinates toward the reference ones.
....hope this helps...dac
