Hello,
I really like your image viewer and I was enthused to find a DTI
display option in it. I am trying to load in a diffusion tensor,
128x128x90x6, voxel size 2x2x2, float32 that is saved in the Nifti
convention (lower triangular, NIFTI_INTENT_SYMMATRIX).

In the information dialog, I select image type: Diffusion Tensor and
display as RGB but the image is still displayed in grayscale. When I
select Lines, I get a few faint blue dots. Modulation by the FA gives me
an overlay of the tensor with the FA and two sliders (still no color or
lines). But I can't get even close to the beauty shown in this document
http://www.fmrib.ox.ac.uk/fsl/fslview/dti.html

Any help would be greatly appreciated.
Thanks,
