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

Hello folks,

(Sorry for the delay, for some reason the message did not post when I wrote it a few days ago.)

As Nick said, there can be many reasons for the discrepancy and in some cases the error will depend on the shape of the ROI.
If you to measure the volume attributed to a surface patch, the best estimate is obtained with SurfPatch. Example 1 in that program's output shows how the volume is computed.

cheers,
Ziad
