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

I'm not seeing an attached image, but I can guess you mean either one of two things:
A) an FA map colorized by local direction of first eigenvector (blue, superior-inferior; etc.); or
B) little, tiny overlay lines per voxel showing local orientation of the first eigenvector.

For case (A), see for example using 3dThreetoRGB:
[afni.nimh.nih.gov]

For case (B), this is really a larger AFNI/SUMA-viewing question, to which I don't know the answer, and hopefully someone more authoritative on such things can supply information.
