Cannot generate BEM surfaces for fsaverage cortex

1

Dear Brainstorm community,

I am hoping to do some source analyses in the context of the Yeo 2011 network parcellation.

From what I gathered, I would have to do my analyses in Brainstorm with the fsaverage template rather than the ICBM152 anatomy. Accordingly, I followed the bottom sections of the freesurfer tutorial:

https://neuroimage.usc.edu/brainstorm/Tutorials/LabelFreeSurfer

I would like to do source analysis, so I first generate the BEM surfaces. However, I run into this error:

This is my current anatomy section:

Any comments as to what I am doing wrong would be greatly appreciated.

Hi,

Which version of brainstorm are you using? In the latest version (20-03-2020) I had no problem making BEM surfaces of the FSAverage model.

Kind regards,
Steven

If you have access to the anatomy of your subjects (or any MRI you want to use as an anatomy template), you can process the MRI in from Brainstorm using CAT12. This would give you access to the Schaefer 2018 atlas (parcellations of the same 7/17 networks)

There is something wrong with your Brainstorm installation.
If you execute bst_get('AnatomyDefaults', 'ICBM152') in the Matlab command window, you should get something like the following:

>> bst_get('AnatomyDefaults', 'ICBM152')
ans = 
  struct with fields:
    FilePath: 'C:\Work\Dev\brainstorm3\defaults\anatomy\ICBM152'
        Name: 'ICBM152'

If you get an empty structure, delete the brainstorm3 folder and download a new version from the website.

Thank you Francois. Redownloading Brainstorm3 fixed the issue.

Best,
Paul
