Hello, 

I have a 3-class mask that was saved in nifti format. When I clicked on the images to view the pixel values, I noticed that those shown in MRIcron were not the same as those shown in MRIcro or MRIcroGL; the latter two showed the same result. I attached an example where the same mask was opened via MRIcro and MRIcron. In the MRIcro, the values showed 2, which is what I expected; in MRIcron, the value is 0. They are not perfectly aligned, but the area around the pinpoint shares the same value. So, it is not an issue of misalignment. I am confused by that. Is it the viewing tool issue, or how I computed my mask incorrectly? Can someone help me with it?

Thanks, 

Cornelia
