It certainly exists:

bigbang% pwd

/bigbang/data/AnnaGroup/caterpillar/parent/gL100X10/outputs/snapdir_000

bigbang% ls

...

snap_000.156.hdf5  snap_000.213.hdf5  snap_000.40.hdf5   snap_000.99.hdf5

snap_000.157.hdf5  snap_000.214.hdf5  snap_000.41.hdf5   snap_000.9.hdf5

It seesm to load but not contain anything:

In [15]: data =
ytf.sph.GadgetHDF5Dataset(basepath+ext,dataset_type='gadget_hdf5')

Out[15]: snap_000
