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

There have been a number of papers published on FMRI test-retest. Shouldn't be too hard to look them up.

Another measure that has been used is voxel repeatability. Threshold the activation map, and see how many voxels are in common between the two days. This can be done in several ways with the AFNI programs, depending on exactly what you want to calculate.
