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 Christine,

Since you want to apply '2..$' in 3dToutcount, rather than removing 2 time points and you and Cesar noted, I will assume there are stimulus events at the beginning of the run that you do not want to manage after they get chopped off, or something similar.

The difficulty with applying '2..$' for computation of MIN_OUTLIERS (or for censoring), is that the results will be 2 time points (per run) off from the rest of the script. So the MIN_OUTLIER would not actually be correct, nor would the outlier censoring, if applied.

There would be much more to adjust in the proc script to account for missing those time points.

Are you trying to preserve early stim events?
Is there another reason you are trying this?
