Hi,
Why are you using -b 0.95,1 with fslview?
This will make your display range 0.95 to 1.0, but all the
interesting values are 1 to 3 in your case, so you will
not see any difference between them.
The number is displayed in the intensity box near the coordinates.
I recommend that you do the tutorial on FSLView which is
part of the first FSL Course practical which you can find online.
This will help you become familiar with how FSLView works.
All the best,
Mark
