Hi there!
Thanks Tim for introducing "bedpost_datacheck"!
As Tim had recommended I inspected the results of DTIfit. Unfortunately none
of the generated maps (except for S0 ) are good. Actually all the values in
the maps are 0. So practically I get nothing!
Here is the results of bedpost_datacheck:

How could i find out what is wrong with it?
I really appreciate your help.
