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

Hi Edward,

I assume that the script you provided is for just one run. You could concatenate all your runs into one file and run 3dDeconvolve on the concateneated file.

I don't understand why you want to flatten the baseline or normalize it. As long as you add "-peak 1" when you run waver and normalize your dataset before you run 3dDeconvolve, those regressor coefficients would reflect their corresponding % signal change. Indeed you could add "-polort 2" in 3dDeconvolve if you feel that a quadratic trend would be a better fitting for the baseline.

Gang
