[Mristudio-users] Problem loading high resolution scans into DTI Studio

[Kevin Spitler]

I haven't upgraded the operating system.  I am still using Windows XP.

Here is the gradient table:

0: 0.000, 0.000, 0.000
 1: 0.500, 0.000, 0.500
 2: -0.500, 0.000, 0.500
 3: 0.000, 0.500, 0.500
 4: 0.000, 0.500, -0.500
 5: 0.500, 0.500, 0.000
 6: -0.500, 0.500, 0.000
 7: 1.000, 0.000, 1.000
 8: -1.000, 0.000, 1.000
 9: 0.000, 1.000, 1.000
 10: 0.000, 1.000, -1.000
 11: 1.000, 1.000, 0.000
 12: -1.000, 1.000, 0.000

Thanks for your help!  Please let me know what else I can send

Best,
Kevin

I am using the same 12 direction gradient that worked on the low resolution (large slice thickness).  Although the DTI Studio program does not crash, the color map 0 generated is not correct (random color patterns over the tissue).
