Dan,
Can I conduct this dynamic cross-correlation map for some (mass) centers?
I tried something like this:
matrix correl name correlation :1.N,CA,:2@,CA,CB out correl.matrix
But I get the correlation separately for each atom, not their center.
Sorry to bother you with this. ^_^

You can't, it is by definition a symmetric matrix.

Unfortunately the 'crosscorr' command currently works with non-vector data
sets only. I think probably your best bet at this point is to use 'matrix
correl' with a mask that encompasses all of the atoms you wish to look at,
e.g.:
matrix correl name correlation :1.N,:2.CB out correl.matrix
In this case the off-diagonal elements in 'correl.matrix' will contain the
information you want.
