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

Try my second approach then:

3dttest++ using one of your conditions as a covariate

If you want to obtain specifically the correlation coefficient, you may use

1) 3dMean to get the mean for each condition;
2) 3dMean -sd to obtain standard deviation;
3) 3dcalc to standardize the data
