[AMBER] protein alignment and rmsd calculation of protein loop

Hi,

       I need to align a trajectory (residues 2 to 169) to a reference pdb
(residues :3-170) and then calculate rmsd of a loop (residues 28 to 35) in
the trajectory to residues 29-36 in the reference pdb. I tried the
following:

        align :2-169&!.H= reference :3-170&!.H= mass
        rmsd p1-atoms :28-35&!.H= reference :29-36&!.H= out rmsd_v10.dat

       I doubt that the loops are being aligned before rmsd reporting and
not the protein part. As I mentioned I need to align the protein part and
then calculate rmsd of the loop part after alignment.
       I need help forming the cpptraj script for executing this.

Regards
Abhilash
