I was given the following (MRI-Studio created) files by a collaborator:<br>
<br>U016_color_map_0.dat<br>
U016_eigen_vector_0.dat<br>
U016_FA.dat<br>
U016_tensor.dat<br>

like to get a tensor file in nhdr format for use with Slicer. I can
use the .nhdr DWI file, but it includes some bad slices that are apparently
excluded in the DTI-Studio processing, which I'd also like to exclude.
Therefore I have three questions, only one of which needs to be
answered for me to obtain my desired nhdr format tensor file.<br>
<br>1) How do I load the tensor.dat file to be saved as a nhdr (if this
is possible) in DTI-Studio, or how do I use other data I have here with
DTI-Studio to create a nhdr tensor file that excludes the slices which
were found to be bad?<br>
<br>2) How do I read the tensor.dat file? If I understand the data format I can convert it to nrrd tensor file format<br><br>3)
Where is this data quality flag information stored, and how do I read
it? I could use the nhdr I have already and remove the offending bad
slices, then estimate tensors without these slices, producing a nrrd
format tensor file.<br>
