[Mristudio-users] Compatibility issue with opening CATNAP tensor images in DTI studio

[XIN LI]

Priti,

There are two selections "DTI-Studio" and "DTI-Map" for "File Format" in the "Open Tensor Image File" 
window. Please try the alternative selection if the tensor file you try to load into DtiStudio or Landmarker
is displayed as black and white lines. That may solve your second problem.



Xin
