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

I understand now. Thank you Gang!
Last question - Say you have a mixed block-event design and the contrast is [1 -1]. For an individual subjects, are the parameter estimates for the difference (A-B) actually %signal change regardless of the scaling as long as its the same for the two conditions (dmBLOCK(0) or dmBLOCK(-X))? Of course, to be able to take this to group level, it would be necessary to have the same scaling factor across subjects right?
