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.
In the case of DTI data, the number of white matter properties are quite limited. However, the number of voxels is quite substantial; in addition, 3dMVM in its current form is not suited for handling the spatial structures among the huge number of voxels in the brain. The underlying modeling mechanism may work for cvMANOVA, but it needs some thinking and coding work.
