function eddy no longer exists in fsl (v 5.0.11)

[JPolzehl]

eddy has been replaced by eddy_openmp and eddy_cuda in fsl. This requires a chaange of the call in function eddy ...

From the fsl/eddy manual:

The eddy executables

eddy is a very computationally intense application, so in order to speed things up it has been parallelised. This has been done in two ways, resulting in two different executables

eddy_openmp: This executable has been parallelised through OpenMP, which allows eddy to use more than one core/CPU when running.

eddy_cuda: The other executable has been parallelised with CUDA, which allows eddy to use an Nvidia GPU if one is available on the system. 

Hence, there is not longer an executable named eddy and when I refer to the eddy-command in the rest of this users guide it is implied that this is either eddy_openmp or eddy_cuda. The eddy_cuda version is potentially much faster than eddy_openmp and not all new features will be available for the OpenMP version. This is because the slow speed makes it almost impossible to test the more time-consuming options thoroughly.
