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

Dear all,

I couldn't find an answer to this issue in past discussions, but it seems simple enough:

Is there a way to use a manually drawn surface roi (either in .dset or in .roi form) to extract stats about the ROI in the surface domain?

Specifics:
1. data are cortical thickness data exported from freesurfer as .gii
2. ROIs were drawn manually in each participant's space

I'd like to get the mean, stdev of all values per ROI, for each person.

Before converting to 1D and coding in R I'd like to know if there's a saner within-AFNI workflow.

Thanks,
Oori
