I tried to define the multiple b-value gradient table (which was editted from
the 30-direction DTI gradient table I used to define and opened the dataset
successfully) for screening the DWI images for further calculation. But every
time it kept saying that "file size is bigger than DW-image size" and
failed to open the dataset correctly. I wonder if there is any mistake in my
