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

# FA
4.130704e-01 4.096045e-01
4.096045e-01 3.369234e-01

Then, what should I write the FA value on the paper?
is it 0.409..?

Yes. Calling your target ROIs #1 and #2, then 0.41 (is probably how I would report it-- two significant figures seems appropriate for FA, perhaps three, but I guess that is a combination of a style and study design choice) is the average FA value in the set of voxels estimated to be the WM connection (=through which a suprathreshold number of tracts passed) between target #1 and #2.

Re. the other values (which are on the diagonal): 0.413 is the average FA in the set of voxels estimated to be the WM passing through at least target #1 (could go through #2, or could not, as well); 0.337 is the average FA for voxels in WM passing through at least target #2.
