I created a label map with 2 segments and gave voxel value 0.4 to 1 segment and 0.6 to the other. The label map in NIfTI format was originated from the NIfTI PET imaging file using 3D Slicer, thus the physical spaces of the 2 images should be exactly the same . All the other correction methods work fine with the PET image and the mask file (label map file) but only MTC failed:
