Hello! I am trying to use the NiiStat function directly (I put it in a script): 

   NiiStat('..\DEMO.xlsx', 5, 7,5000, 0.10, 3, 0, file.nii, 0, 0, 0, 0)

It seems the third argument, "7", should denote that my modality is DTI. However, when I try to run NiiStat, it prints out a number of things, and among them is

   Analyzing roi=0, modality=1, permute=5000, design=DEMO

So my modality seems to be set to "lesion". My output folders also begin with "lesion_". Why is my modality input not being used? And does this matter? I'm wondering if I can still use stats from outputs which were called in this way. I'm worried, however, that maybe information is lost in conversion from .nii to .mat if NiiStat assumes that my file should have values from 0..1, for instance.
