[Freesurfer] Avoiding or removing overlap when converting surface labels to volume

External Email - Use Caution

Hi Freesurfer team,

I am transforming several adjacent surface labels into volume ROIs, using *mri_label2vol*. When doing so, there seems to be some possibly unavoidable overlap in a small number of voxels in the volume ROIs. Is there any way to avoid these labels from overlapping when transformed into the volume? I see that *mri_label2vol* takes an --annot flag, would this help in avoiding overlap in the outputs?

Otherwise, I can remove the overlapping voxels int he nifti file outputs, but I was wondering if the algorithm had any options to do this as part of the surface-to-volume transform.

Thanks so much! Jacob
