[Insight-users] SimpleITK and DTI

[Bradley Lowekamp]

Hello,

SimpleITK does not have currently have support for images of tensors. I would like to add some basic support for this in the near future.

This is where you exception is coming from:
https://github.com/SimpleITK/SimpleITK/blob/master/Code/IO/src/sitkImageReaderBase.cxx#L86

What were you hoping to be able to do in SimpleITK? What algorithms/filters were you hoping to do?

I am hopping for some users to help drive and test this addition to SimpleITK.

Thanks,
Brad
