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

Rick, thank for the fast reply! I understand the need for a baseline here and the ambiguity issue. The original study was designed only to look at relative differences between conditions and not activation levels for any one condition per se. Given that 3dDeconvolve will still produce a beta for each condition, can you help me understand how to think about what that means? Does it make sense to think of it as deviation from a voxel-wise mean that includes the other two conditions?
