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

Hello AFNI Team,

I am trying to input ROI data from an experiment into the Sleuth application from the Brainmap database. My only issue is that the irregular ROI has too many voxels for the Sleuth application to handle all at once. Could someone reccomend a solution on how to split my original ROI image into several (ideally 4) smaller ROI's that could be added to equal my original image? My goal is that by feeding separate, smaller ROIs into the Sleuth application, I can still get the related data I need. I understand 3dcalc may be able to help, but specific suggestions on how to approach this problem would be greatly appreciated.

Thank you,

Will Snyder
