This is currently failing on travis (https://travis-ci.org/nipy/dipy/jobs/20637708#L3325). I wouldn't put this in the `__init__.py` file. Instead, put this in the test itself, if you really need it. Also, if you want to read files, use the schemes that exist in `dipy.data`. Is it possible to use one of the data-sets that is already defined there for this test? That would be preferable, I would think
