[Insight-users] Problems detecting ImageIOBase::MATRIX

[Ariel Hernán Curiale]

I found in the header of the images that have the same type of kinds (kinds: vector domain domain ).  I can read both images but I need to force the type (Vector or Matrix).
According to the .nrrd definition the kinds of the image (Matrix) must not be a matrix ?

Saludos
