Displaying the segmentation results in 2D is a bit more complicated, but this is just because to keep the underlying memory management as fast as possible. The desired ROI may be loaded with METKROISelect and displayed with METKViewer2D. If you want to display the segmentations as a colored overlay, you first have to generate a combined segmentation mask, containing all segmentation results for the given ROI. This is done by using METKCodedSegmentation. The generation takes some time, but the result will be stored at your hard drive and will make the future image display much faster, because only one extra image has to be loaded (instead of one image per segmentation). The result of the combined segmentation mask may be displayed with METKOverlay2D.
Needed modules: METKCodedSegmentation, METKOverlay2D, METKROISelect, METKViewer2D
