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

Hey Rick,

We have a quick questions about calling detrend in 3dFWHMx.

First, since afni_proc already detrends we figured the residuals would already be detrended. Would you expect running detrend with 3dFWHMx on residuals to have considerable impact since they should have already been detrended by afni_proc.

Second, since afni_proc detrends for each run could some of the differences we are seeing be explained by the fact that when we estimate the blur from the residuals its is the full concatenate set of runs and not the individual runs themselves?

Thanks

Steve
