[AMBER] Is the RMSD using ptraj normalized with respect to residues ??

Hi folks,

I am using ptraj to calculate the RMSD of amber trajectories
with respect to initially minimized structure. Here is the command

rms reference mass out rms_trj time 1

I calculated RMSD for full structure (~ 50000 atoms) and it came ~ 1.1 nm,
while for few residues (350 atoms) of this structure RMSD is also near 1 nm,

Does the rmsd I got is normalized over no. of residues or I am missing
something
else. Kindly comment.

Thanks
