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 current slice-based regressors provided to afnI_proc.py are already seen as regressors - they are not manipulated, except for possibly removing some time points from the start of each run. Therefore, if you could insert additional regressors to make a larger file (more regressors per slice), the updated file could be fed without any changes to afni_proc.py at all. At least, I believe that to be the case.

Peter is currently working RetroTS.py, and might be interested in this operation. Are you going to convolve as in: for each time point, put down a basis function scaled by the unconvolved RVT? Which basis function do you plan to use, GAM? BLOCK(1)?

Thanks,

- rick
