Hi Nils

 

There are expert options for this. You can specify things like -min_white 90 to some of the programs like mri_segment and the surface placement stuff

 

Cheers

Bruce

        External Email - Use Caution        

Hello everyone,

 

I just have a short question, because I can't find anything helpful in the tutorials.

 

In my MRI scans freesurfer includes areas to the white matter, even though visual inspection concludes that the area should be grey matter. Is there a possibility to change the value at which freesurfer includes areas to the WM, which i can just change? For example freesurfer includes areas to the WM with intensity values below 85 and i want to change that.

 

I'd be thankful for any feedback/links to guides.

 

Best regards,

 

Nils
