Dear AFNI users-
We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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 - what is the best way to calculate the number of vertices in a specific anatomical region above a given q threshold?
Thanks!

Perfect thanks. And lastly, how can I resolve alignment issues between the pial.gii files and the scalp.stl file?

Great. When loading requested surfaces on the command line, is there a way to make the scalp surface transparent?

Hi,
I am looking to visualize surface activation with a (transparent) scalp mesh stl file overlaid on top. I have been using SUMA to view cortical activation so far. What is the recommended way to do this?
Thanks!

Thanks. And last question - why do I need to subtract 1 from the number of nodes when I convert the ROI to a dataset in order to match the number of nodes in the spec file for SurfMeasures?

Ok thank you! What is the best way to find the length of the node list of the spec file for SurfMeasures?

Hi - wanted to follow up here to check if there's a solution for this. Thanks!

Thanks for your quick response, Daniel.
I think I'm doing something wrong, because my dset file is a bunch of random characters (see screenshot attached) and 3dBrick Stat is giving me the following error:
(base) ashamehta-mbp:mri_ODP663 ashamehta$ 3dBrickStat -sum test.niml.dset'[1]'
** ERROR: selector index 1 is out of range 0..0
** ERROR: bad sub-brick selector [1]
** FATA

Hi,
Is there a way to calculate the surface area of ROIs drawn in SUMA? SurfMeasures seems like the appropriate program, but I'm not sure how to process the SUMA ROI into the input spec file.
Thanks in advance.
