Just grepping through the MetaIO headers, it looks like BayesianClassifierInitializerMemberships.mhd has 4 channels per pixel, and itkBrainSliceComplex.mha has 2 channels per pixel.

Thanks a lot Dave. Didn’t occur to me to check the headers. Looks like those are the only 2 mha and mhd files with vectors.
