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

The datasets that end with "mpm" are "maximum probability maps", really the maps of the regions that give the maximum probability at each voxel, rather than a specific probability. You could use a ventricle mask from the N27 dataset in MNI space. Download the N27 surfaces and volumes in MNI space here:

You could use the ventricle mask dataset, aparc+aseg_REN_vent.nii.gz, as a mask. Take a look to see if that's what you want.
