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

The regressors form the columns of the X-matrix, which are
regressed against each voxel time series. So the regressors
need to be TR-locked against the data, having the same number
of values/TRs.

That is to say your regressors should be on a 2-second grid.

3dDeconvolve expects this, and so looks at only the first 256
values in your regressors, which are all zero for those two
regressors.
