No standard head model was found for subject bem in D:\MEG Data\Imaging\Par004_bem

Hi all, I am trying to run coregistration ( mne.coreg.Coregistration)

I get this error:
“No standard head model was found for subject bem in D:\MEG Data\Imaging\Par004_bem”
Do you have any idea what the problem is?
BTW, freesurfer is not installed on my machine. Does it have to be installed to use the above function?
Thank you!

  • MNE version: 1.6.0
  • operating system: Windows 10

going through the corresponding tutorial, I see mention of fsaverage, which makes me think that you would indeed need freesurfer.

But not 100% sure on this.
