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 Pete,
Well, what I'm thinking is that there are two options.
One is to extract the surface from Brainstorm with the data/values on it and import into SUMA, assuming the weird smoothing that alters the sulcification isn't imported along with it.
OR to export the data on the surface from Brainstorm as a NIfTI that's coregistered to the subject's anatomical used to ge

That's a relief to hear! Here's the command I use to load the file and the output that follows.

Hello!
I am wondering if there is any way to view an inflated version of *.gii surface files SUMA. The surface I am interested in inflating is a surface from an MEG data analysis software (Brainstorm) that I am interested in viewing in SUMA. This gii file is exported from the MEG software specifically for viewing in SPM, and it is possible to see an inflated view in SPM from this gii file, but

Hello,
I'm working on a project that compares activation as measured by MEG compared to fMRI (I'm on the fMRI end). The MEG data has been processed and projected onto a surface through Brainstorm while the fMRI data has been processed in SPM then projected through SUMA.
In order to make the distinction between the two methods as obvious as possible, we are trying to make the corti

Thanks you, the plugin was good advice. I had seen advice about it elsewhere on the message board, but I am so new to AFNI that I had no clue where to even find the plugins.
I basically have exactly what I want now, just one trivial question. In the object controller of SUMA, is there a way to adjust the intensity scale so that it only displays a positive range as you can do in the AFNI overla

Hi Daniel,
Sorry for the intensely late response and the vague question.
Here's what I have:
1. surfaces converted from FreeSurfer of the subject's anatomy
2. a NIfTI file with a frequency tuning map (each voxel has a value range 1-8 depending on the frequency it activates most highly to) generated through an SPM analysis
What I would like to do:
1. project the tuning map o

Hello!
I am attempting to project an ROI (in NIfTI format), which is a collection of about 450 individual coordinates all around the auditory cortex (both hemispheres), to a surface. Unfortunately, when I load the ROI, it shows up as maybe 30 coordinates, still in the correct region, just not nearly as many as when viewed on the volume. If I load the smoothed version of the ROI, it looks compl
