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.
You are now comparing different computations with finite
numerical resolution that should only theoretically arrive
at the same result. Particularly with scaled short data,
you should expect different truncation errors. If you had
float data, the results would probably be closer.
The images should be almost idential, but surely with small
differences.
