Check choice dwi b2000 source file

Lifebid version looks cropped with respect to the original one from HCP.

I do not understand this comment.

The original dwi files from HCP have size (145,174,145).
While the ones preprocessed in lifebid have size (129,169,121).
It means that probably the images have been cropped.
