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

Paul,

It seems that what you want isn't exactly the full residuals, but the data with the covariates projected out. That is, using Gang's notation, after the voxel-wise fit is made (giving the b.. coefficients)

yi1 = b01 + b11 * covi1 + b21 * covi2 + ei1

for the data in the ith subject in group 1, then you want the modified data

zi1 = b01 + ei1

to be written out to a dataset for further messing around. Is that right?
