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 default zeropadding was reduced to save memory. For high resolution datasets, the former default of 40mm on all sides could make some datasets exceed the memory capacity of even very large servers. Alignment would also use vast amounts more (~18x). The zeropadding helps to allow for tilting of the brain inside the dataset grid but may only be needed for very oblique datasets.
