I have been trying to use FDT for DTI and I have come across a problem.
My data consists of a 4D set containing 1 b0 volume followed by 25 direction
volumes at b1000. I have bvals and bvecs set each with 26 entries (1 dummy
entry at the start in bvecs and the first bval set to 0) and a single brain
mask volume produced using BET on the b0 data volume.
However, when II run FDFIT on this data it produces blank results for all
except the _S0 volume.
Can anyone suggest where I am likely to be going wrong? It does not appear
to be a software problem as I have the same problem running it under linux
Thanks for your help
