I am having a couple of problems.
Can someone tell me how to fill in the bvecs file correctly? The
information I have about the gradient directions in the 30 b direction
sequence I am using shows x, y, and z the absolute values of which add up
to one as in the exerpt below.....
1 0.4356 -0.226576 -0.770884 0.004225 0.734449
0 0.564001 0.343396 0.145161 0.613089 0.112896
0 0 0.430336 0.0841 -0.381924 -0.152881
Do these need to be modified to represent true vectors?
I get a good FA map with these, but the V1_RGB looks very smearedn and the
colours are mostly pretty pastels, rather than good strong blue, green,
and red.
Also, I can run the tools from a command line , but I get an error if I
try to use the GUI. Here is the message.....
bad cursor spec " watch red white "

Thanks for this great tool and any assistance you can offer to get me up
and running.
