Eric,
No, 'Dark_Matter_Density' does not work, either...
-> similar error:
In [5]: pc.add_slice('Dark_Matter_Density', 0)
Exception AttributeError: "EnzoHierarchy instance has no attribute
'_data_file'" in <bound method EnzoHierarchy.__del__ of
<yt.lagos.HierarchyType.EnzoHierarchy instance at 0x2aa1cfbcf8>> ignored

I think it is I did not set the "data_style" right...
Thanks,
