[Mristudio-users] problem calculating Tensor, ADC Map

Hi,
I am able to load my data into DTI Studio and can (on the DtiMap tab) run
Original ADC Mean STD
Mean (DWIs, B0s)
My problem is that when I try either Calculation >> Tensor , Color Map, etc
or Calculation >> ADC Map
I get completely black views for axial, sagital, and coronal (and the
3d view in the upper left). I do not get an error message. What
could be causing this?
I get the same results regardless of choosing "create a mask image
based on the background noise level 10" or choosing to "Select a mask
image b0"
I am using DTI Studio 3.0.3 (Sept 2010) on Windows 7 OS.
My old data files load and I can do tractography on my old data.
I am using Siemens Gradient:
0: 0, 0, 0
1: 1.000000, 0.414250, -0.414250
2: 1.000000, -0.414250, -0.414250
3: 1.000000, -0.414250, 0.414250
4: 1.000000, 0.414250, 0.414250
5: 0.414250, 0.414250, 1.000000
6: 0.414250, 1.000000, 0.414250
7: 0.414250, 1.000000, -0.414250
8: 0.414250, 0.414250, -1.000000
9: 0.414250, -0.414250, -1.000000
10: 0.414250, -1.000000, -0.414250
11: 0.414250, -1.000000, 0.414250
12: 0.414250, -0.414250, 1.000000
Thanks for your help
Kevin
