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,
I have managed to create regions of interest via 3dmerge. When I set the fbuc mask as the overlay I can see where I am getting significant clustering. I was wondering if there is a way for me to click on a pixel and have the computer define all contiguous pixels in every direction (i.e. contiguous voxels) as one region of interest so that I can do statistical analysis on each ROI. If there is a command line way to do essentially the same thing, that would be even better. As of now, It looks like I'll have to go through each slice and manually click on contiguous pixels throughout the brain. Can anyone suggest another way to do this?

Thanks,
Matt
