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

Howdy-

The following datasets involved in this should all have the same grid/resolution:
+ the 4D dataset used to estimate the ACF parameters with 3dFWHMx
+ the mask dataset used for delimiting the brain in 3dFWHMx, and which will be provided to 3dClustSim
+ the statistics dataset that will have the clusterizing applied.

Perhaps, in theory, some of those probably *could* be on separate grids, because of the stability of resampling within AFNI:
[arxiv.org]
... but in practice, there is typically no reason to have any of those on a separate grid, and it would be *very* easy to mis-apply parameters or estimated quantities. If you are using afni_proc.py, all of the output dsets involved should be automatically on the same output grid anyways (I think...).
