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

AFNI datasets can be made of data stored as integers or floating point numbers among a couple other less used types. If the datasets are in integer format, each sub-brick volume may be scaled by a floating point factor. Although this format saves disk space it also suffers from precision issues, average non-zero error in precision is shown in the warning. For a good detailed description of the warning, see this previous thread:
