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.
This is expected, and is because of the 'scale' processing block (which notably does not affect correlations, nor does the censoring).
The voxels inside the brain have noise that may be somewhat similar to what is outside the brain. However, they also have far higher means. So when all voxels are scaled, the fluctuations outside the brain are heavily amplified when compared with fluctuations inside the brain.
