All,

I think afni should have a 3dcorrelate.
The purpose of this tool would be to produce a Pearson r correlation coefficient for two subbricks from one file or one subbrik from each of 2 files.

Bells and whistles:

(1) a scatterplot that could be saved as .ps file.
(2) non-parametric Spearman correlation option.
(3) df and p-values.
(4) linear equation (slope and intercept) relating the 2 subbriks.


Anybody but me interested in this option?
