Error loading models in FreeSurfer extension

Support
1

Hello,

I am trying to use the FreeSurfer Importer to import surface data into slicer. I’ve checked using Freeview that the data can be loaded and visualized, however when using the slicer’s extension an error occurs when loading the files. The log shows this:

Error: Loading /Applications/freesurfer/7.4.1/subjects/sub-CON006/lh.surf.white - Could not load file: /Applications/freesurfer/7.4.1/subjects/sub-CON006/lh.surf.white

Would be grateful for any help! Thanks in advance.

Can you send a link to the full log?
I can also take a look at the model if you can send me a link.
