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:

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

Thanks, I'll try to play with these this week.

What I am trying to do is to take part of a 3x3 design and put it in a 9 levels of one variable, and then use linear contrasts to recover the 3 x 3 design:
ME1 = [1 1 1 0 0 0 -1 -1 -1; 1 1 1 -2 -2-2 1 1 1]
ME2 = [1 0 -1 1 0 -1 1 0 -1; 1 -2 1 1 -2 1 1 -2 1]
Inter = ME1.*ME2 (4 vectors)

Before jumping in, I just wanted to make sure that this is the correct way of setting up the contrasts.

And again, thanks again for all you help,
Best,
Wil
