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

[Kevin Spitler]

I am using the same gradient table as before, which worked with the low
resolution data (large slice thickness).

We are using a 3T Trio scanner in Siemens.

Would it help if I attached one of the files from a recent scan?

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).
