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 pt,

Thank you (always) for your help and quick response.

Yes, the txt file has 3 columns (x-, y- and z-coord values). Could you clarify what should be the 'ROI value' in the 4th column? I attached a screenshot of Power et al. (2011)'s coordinate excel file. The 4th column should be the Master Assignment column that divides the coordinates into each network (e.g., DMN, DAN etc)? Would you suggest that the txt file should look like below (I just put some random numbers)?

x y z network
10 20 30 1
5 15 25 2

I didn't see the warning message though. Below is the message that appeared when running the 3dNetCorr.
