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, Marina-

This post describes how to do it with Surf2VolCoord:
[afni.nimh.nih.gov]
Basically, you put your coordinate location into a text file ("x y z" values in one row), preferably using RAI DICOM coordinates, and then you can get the closest surface index (and the Euclidean distance between your coords and that point). It might also be a good idea to doublecheck things in SUMA.

Here is a set of SUMA-generated standard surfaces and parcellations for the MNI 152 brain, if you don't have it already:
