Subject: AMBER: matrix correl
Did this problem ever get diagnosed?
DLB
Dear Amber users,
Does anyone have experience with correlation facility in Amber8? The
residue-residue correlation map of "matrix" command has diagonal elements
are not 1! It's weird because I thought the residue will move correlated
with itself during the simulation; thus, the correlation should be 1.
Here is my input file for ptraj:
trajin corr500.crd.gz
center :1-534 mass origin
image origin center
rms first mass out rmsh.dat :1-534
matrix correl name corr :1-534 out dccm byres mass
And here is a part of the output file (534x534 matrix, I took only 10x10
matrix):
0.89 0.66 0.37 0.29 0.13 -0.03 -0.24 -0.27 -0.20 -0.08
0.66 0.89 0.58 0.42 0.25 0.03 -0.07 -0.19 -0.12 -0.08

-0.08 -0.08 0.12 0.32 0.39 0.56 0.46 0.68 0.80 0.85
Any hints?
