I've been having some trouble with DTI fit. Sometimes when I run it, all the
resulting datasets are empty.
I suspect that the problem may be in how I produce my bvals / bvecs files.
Sometimes I do them by hand, sometimes, its copy and paste from another
file, sometimes I'm scripting it to read from the GE tensor.dat file. They
always LOOK the same
e.g.
bvals:
0 1000 1000 ...
bvecs:
0 0.707 0.707 ...
0 0.707 -0.707 ...
0 0 0 ...
I suspect that it has something to do with whether i'm using spaces or tabs,
if there's trailing spaces at the end of line, what kind of carriage returns
are being used, etc.
Any suggestions on what works and what doesn't?
