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

Dear AFNI Gods,

I was curious what warning messages about "handedness" from 3dAllineate mean and what information they are based off of. I ask because my lab has been wrestling with a potential "left-right" reversal problem for some time (we were unconvinced that left=right as advertised at the bottom of the image). After running scans on a phantom with a water-filled syringe to one side, we thought we had solved the problem: that both the anatomical and functional scans produced images where left did in fact equal right.

You can see why this error message, generated when aligning the functional to the anatomical images, bothers me.
