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

1) How did you analyze your data with the waver output ideal.1D?

2) You can remove baselines with the 3dDetrend program. However, this is not recommended, since the baseline and your regressor may not be completely orthogonal. (See the 3dDeconvolve manual for an example.) Since the AFNI data analysis program do detrending along with the analysis, I'm not sure why you want to detrend so badly. In any case, if you average the datasets BEFORE detrending, you'll just average the baselines, which will give you an average baseline, which you can remove or regress out as normal.
