Import other freesurfer maps?

Discussions

Hi,

is it possible to import freesurfer maps other than the thickness, e.g. curvature?

I assume there is some way to this as it basically the same format as the thickness maps?

best,

Hello,

I think the three only types of files you could import from the FreeSurfer surf folder and display as cortical maps are: the thickness, the sulci map and the curvature map.
The curvature is recalculated in Brainstorm (and saved in the field .Curvature of the surface files).
When I wrote this import function, I thought that the only file of interest could be the thickness map.

If you want to import other files in a quick and dirty way, you could edit the file “brainstorm3/toolbox/io/import_anatomy_fs.m”.
Either add or replace the blocks that import the thickness maps (line 164-165, line 459).

Cheers,
Francois

Hi Francois,

Good afternoon!

May I ask you how to read cortical volume for each atlas or lobe based on your brainstorm?
I can read curvature and thickness based on the content you import from freesurfer, but
I do not know how to import volume data.
You know the detailed of freesurfer folder. If possible, give some tips, or code.

Best wishes,
Junpeng

Hi Junpeng,
I’m sorry, I don’t know how to access the type of information you are looking for.
Maybe you should ask the freesurfer team instead.
