I was wondering if anyone could help me with some DTI stuff. I ran DTI on some subjects but when I get the V1, V2, V3 files and try to look at them modulated with the FA files, they are one solid color. I run through the tutorialat (http://www.cabiatl.com/CABI/resources/dti-analysis/) and made nice track graphs, but exactly the same process on these subjects gives me a solid picture instead of tracts.
