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.
If you transform your data to Talairach coordinates using AFNI, then after you mark the lesions somehow, you could extract the number of marked voxels in various regions of the brain using the Talairach Atlas database builtin to AFNI -- that is, get the number of marked voxels in (say) the cingulate gyrus.
