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

Hello Gang et al.,

I have a 3dLMEr modeling question I am hoping you may be able to help with.

Is it possible to specify multiple contrasts in one model? Essentially, we have a Negative, Neutral, and No Distracter (none) condition. We want to first contrast both distracter conditions with the no distracter conditions, and then contrast the results with each other: (Negative > None) > (Neutral > None). Could we use something like this in the 3dLMEr model specification: -gltCode neg-neu 'emotion : (1*neg -1*none) - (1*neut -1*none)'

Thank you in advance!

Amar
