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

Gang,

Thanks for this info. I tried both methods above to do a T-test between groups X and Y using the PPI effect of conditionA - conditionB.

I was wondering if you could elaborate on the differences between using method 1 (or 2, since they're equivalent), and adding something like:

-gltsym 'SYM: condA -condB' -glt_label 1 condA_vs_condB

to the 3dDeconvolve call for each subject, and then doing the T-test on the coefficients of that sub-brick?

Thanks,

Gustavo
