What do you mean by strange results? Some figures describing the results would help to give you further help.
You talked about 4 layers so i presume you used Skin, Skull, Brain and Lesion? Are these nested compartments? Could you show some visualisation of the meshes/segmentations you used?
seg_i = ft_datatype_segmentation(segmentedmri,'segmentationstyle','indexed');
cfg = ;
cfg.funparameter = 'seg';
cfg.funcolormap = lines(6); % distinct color per tissue
cfg.location = 'center';
cfg.atlas = seg_i; % the segmentation can also be used as atlas
