fNIRS data (no MRI) & surface projection, suma


I am using afni programs to run 3d analyses on my fNIRS data. Now, I’m interested in projecting images onto a brain surface. Is this possible with just fNIRS data and afni tools, or must I have MRI structural data, too?

Thanks for any advice,

You can map all kinds of data onto a surface and view them with suma. We typically use a niml or 1D text format that encodes columns of values that correspond to the surface nodes. You can make additional surfaces like spheres or use a brain surface to give them a place in space. While it’s not exactly the same thing, we do something like this for the ALICE software for ECOG. If you would like, you can send me a message or email for more discussion.


Thank you for replying. I am going to put the surface projection on hold for now finish up the paper I’m working on. I will reach out to you once I get there!


Pursuant to this point, Daniel has constructed a nice tutorial about different ways (no less than 5!) to make+view spheres in SUMA:

These could be combined with some of the automatic snapshotting capability of SUMA, too; for example, see here:
