[FieldTrip] Editing Vertices of Scalp Manually or Automatically

[Isaiah C. Smith]

Hello Everyone,

I am having a problem with noise appearing in my volume conduction model. There are a few horn-like images on the head, and a cluster of vertices in the area where a neck would normally appear but the MRI was only of the upper half of someone's head so it should not be appearing either. I am running into a wall when I try to edit manually because the data so large I cannot view it. Please, I have been trying to fix this for a while does anyone have any ideas on how to get rid of these extraneous points: whether manually or by shifting parameters in the segmentation process? Your help would be extremely helpful and greatly appreciated.

This is an image of the problem described.
