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

Brad,

I don't exactly understand what you would like to do, but I wonder whether the -glt option in 3dDeconvolve would serve your purpose.

By defining various stimuli and baseline in 3dDeconvolve and setting an appropriate contrast test expression with the -glt option, you could get a 't' map at your will.

For the particular example you mentioned (all stimuli vs baseline), the t value corresponding to each regressor coefficient is already a 't' map. The time points are just implicitly expressed in the intervals spanned by those regressors.
