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

Kati,

You are correct -- for a single run, the Run#1Pol#0 is the coefficient of the function '1'.

For this to be the correct baseline, it is important that when you ran 3dDeconvolve to setup the matrix, you did NOT use the -nodmbase option. If you DID do that, extra baseline regressors (such as motion parameters) that you added to the model would also have nonzero means, and the baseline constant would be shared between the betas for those regressors -- making a mess.
