Dear Salil,
when you process your diffusion weighted dataset using the dtifit routine implemented in FSL, you will get, amongst the other output files, one that ends with “_MD.nii.gz”.
That is the mean diffusivity volume, which is what you are probably looking for.
Cheers,
Matteo

To clarify, the trace image to which I am referring is the diffusion weighted image that is routinely used in clinical practice, generated automatically by the MRI scanner, for evaluating the presence of strokes.
