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

Hi Emily,

So there are 2 runs of data, right?

Since the gPPI regressors are in -stim_file
format (columns of numbers), those files
should be zero-padded to be 2 runs long.

For example, if there were 100 TRs per run,
then the run 1 regressors should have 100
varying values followed by 100 zeros, while
the run 2 regressors should have 100 zeros
followed by the varying values.

The seed regressor should be 2 runs of
varying values (200 lines).
