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 everyone,

I'm not sure if anyone would be able to help me out with this.

But here it goes:
I have a functional connectivity (correlation coefficient) matrix derived from fMRI . I have 5 Networks I'm looking at (i.e. DMN, FPN, SN, etc) - each of which have 10 ROIs'.

When I want to do a statistical analysis I don't want to do an ROI-ROI t-test and then a post hoc and correct for the ROI's. Instead I wanted to compare networks.. and if there is a statistically significant difference between two networks, I want to do a post hoc test to see which pair of ROI's contain the difference.

I hope that makes sense. Do you know if there's any toolbox or command that may able to help with this?
