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

An update:

MIN_OUTLIER, as a vr_base (and further as a by_run_vr_base) works incredibly well. Rick and Paul win this one. The noise is high, but MIN_OUTLIER also succeeds in finding a reasonable target nevertheless.

The edits I made, to use mean images does work well and makes nice clean images to inspect however its not as beneficial as I had hoped.

I have concerns that alignment to anatomy would benefit from a mean image (after volume registration) but thats a separate issue. I am also curious how even noisier data would work - perhaps the editing would be needed - but for now, AFNI and the AFNI crew claim another victory.
