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 Paul,

Thanks for your reply. I am sorry, it was my mistake! I used "3dBrickStat -positive -count" to show the ROI size, and it reported the sum size of several ROIs.

I used a A-B_#0_Coef brick of 3dDeconvolve result, restricted to same anatomical area between subjects first, as inset for 3dROIMaker to make constant sized GM ROI near the activation peak (-only_conn_top 500) which showed preferred response to A than B (-thresh 0), and the values in the inset should be contiguous, I did not use -refset, why in some exception it caused multi ROIs?

Thanks,
2086

Why does 3dROIMaker not produce GM ROI size equal to -only_conn_top N?
