I'm relatively new to FSL. I'm having trouble with both DTIfit and
Bedpost. Firstly, when I run DTIfit, I get no pictures, apart from the
SO. It is just black, and comes up with a 0 to 0 brightness range, with
no effect if I alter the numbers to 0 to 1. The S0 comes up as an
anatomical looking picture. The same thing happens regardless of the
numbers I use in bvecs/bvals, as long as there are in the correct format.
When I run bedpost, I end up with a mostly blue brain (range 0 to 1), with
scattered coloured pixels, but not what I would expect! Bedpost_datacheck
goes through without problems, and bvecs is normalised. This is
regardless of whether I eddycorrect or not.
Any suggestions? I'm stumped.
