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

You can add options -cbucket and -x1D in 3dDeconvolve to obtain all the regression coefficients and the model (design) matrix. Then get the effects of no interest:

3dSynthesize -cbucket CbucketFileFrom3dDeconvolve+orig -matrix x1DFrom3dDeconvolve -select ... -prefix EffectsOfNoInterest

And finally have the "cleaned" data by removing the effects of no interest from the original signal with 3dcalc:

3dcalc -a InputFor3Deconvolve -b EffectsOfNoInterest -expr 'a-b' -prefix CleanedData
