I know that the segmentation plugin only creates unsigned short image but the user can load his own binary image created with another tool. Most of the tools work in the OLD segmentation plugin (I didn't test the multilabel) except:
Threshold, UL Threshold
and Fast Marching 3D. Possibly also for Region Growing 3D but I don't have the data to test.
At least, it's easy to understand the problem with these images :)
