AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

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?

Lee
