Hello freesurfers, We've seen some poor surface reconstructions due to local inhomogeneities that remain in the brainmask volume. We see omission of significant portions of brain tissue due to signal fall off (both gray and white voxels are darker than in surrounding area) that we are unable to current through control points or other manual interventions. Can anyone suggest a tool for correcting latent local inhomogeneities? Is anyone aware of a manual tool that allows one to "brighten" the voxels from some point outward at some falloff rate?
Any help would be greatly appreciated.
Best, Jason
