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

Yes that makes sense. Thanks alot.

One more question, if you don't mind. Let's say we use CSPLIN (3,12,4) and then do a contrast between 2 conditions at one lag. e.g:

+cond1[1] -cond2[1]

Will the coefficient that is printed for the glt at each voxel be the DIFFERENCE of the IRF's for each condition for this at this timepoint?
i.e. will the coefficient = IRF.cond1[1]-IRF.cond2[1]?

In the 3dDeconvolve documentation, it indicates that the coefficient will be equal to hr[1] - he[1]
(see pg. 45, example 1.4.4.3)

thanks again, nicola & mb
