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

Thank you so much for explaining. I understand now why the "single variable" GLT was not actually single variable; it includes both SPMG2 parameters.

If I use 
-gltsym 'SYM: SA[0]' -glt_label 4 SA_0
, why would that be different from just looking at the first parameter estimates for the SA regressor? What does doing the GLT add in this case if there is no contrast? I have certainly read that most people only use the first parameter, so I'm particularly concerned that my results for that parameter alone don't look good, but the result for the two combined looks great.
