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

You've got me worried!
I thought the R-squared stat was a basic part of the connectivity analyses as outlined by Gang Chen. That's what I've been using. I also know of some San Diego AFNI users who also use the rout option for their functional connectivity analyses.
As well, I thought that 3dREML was particularly relevant for connectivity analyses. I assumed it was to be used for both the seed voxel identification and subsequent connectivity assessments.
This morning I just presented a PPI result using a 3dREML-based seed voxel predictors and the old reliable 3dDeconvolve to estimate the strength of the connectivity. You might say I conducted a mixed methods PPI connectivity analyses.

So, should I be using 3dREML to estimate the connectivity magnitude as well as the seed voxel?
Thanks.
Darren
