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

Hi, Rebecca-

An example of setting up 3dMEMA with gen_group_command.py, combining masks from individual subject analysis to make a group mask, running the 3dMEMA command, extracting estimated parameters for the "mixed ACF" for 3dClustSim simulations and using 3dClustSim is provided in the "s.nimh_group_level_02_mema.tcsh" script here:
[afni.nimh.nih.gov]
And that associated paper provides some discussion of the rationales for various pieces. I think that addresses pretty much all of the points you asked about above, but please ping back with any it doesn't and/or further ones.

NB: that paper+associated code describes ways to correct a processing stream that another group was doing, and for comparison's sake we could correct MOST of them, but not all of them-- we try to further point out in the paper preferable steps for analysis.
