Hi again, yes, the segmentations, which are saved to file, contain only a binary mask, i.e. 0 for background, 1 for foreground. The data type is "unsigned char", which is usually 8 bit (also for Linux64, I think) -- this is only guaranteed for segmentations which were created from the InteractiveSegmentation GUI. The "File/Save Project" entry is broken and should be removed. There will be a replacement for it -- no schedule, sorry. > > So does that means MITK can not get the segmentation with both > position and grayscale value?

When segmenting with InteractiveSegmentation and saving the result, you have two files: the original image (any image format, your choice, grayscale values, NOT created but only used by InteractiveSegmentation) and the segmentation (unsigned char, zeros and ones, saved by InteractiveSegmentation).
