Dear amber users,
I am using ptraj to determine the diffusion rate and correlation time of a
trisaccharide, from two 10-ns MD simulations. The only difference between
the simulations, is the retention of translational and rotational COM
motions in one (nscm=0).
The graphs I get from the ptraj correlation analysis, do not decay smoothly.
I have attached the graphs I get from the ptraj analysis.

Here is my input:
1. Correlation:
trajin md.crd
correlation cor2 :3.C1 :3.H1 1 20000 20000 out res3C1_res3H1_corr.out go

Any help will be greatly appreciated. I would also like to know what the
three columns stand for.
Thanks,
austin-
