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

While I can make some guesses as to what is going on here, it would be helpful to see your script (or the relevant parts) and the output of 3dinfo -verb YourROIDataset+tlrc. How did you create your ROIs?

That said, it sounds like you are using 3dmaskave, which can work with the "newer" range selectors. If you wish to only extract values for an ROI that has a value of 3, you could do something like this:

3dmaskave -mask ROI+tlrc'<3>' dataset+tlrc
