Dear users,
I generated dense head surfaces for a few subjects using mne.bem.make_scalp_surfaces, after conducting surface reconstruction with Freesurfer’s recon-all. Many of these dense surfaces contain non-head points: see images below, where the dense surface from one subbject is visualized in the MNE coregistration GUI (I have masked out the subject’s face for anonymity).
I tried re-running make_scalp_surfaces with different threshold values, but this makes zero difference to the output. What’s the best approach for improving these surfaces?
- MNE version: 1.9.0
- operating system: Linux
