[Mristudio-users] problem calculating Tensor and ADC Map

[Kevin Spitler]

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.
I attached screen shots of the problem.

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
