from snaptools import snapshot
snap = snapshot.Snapshot('tests/galaxies0.hdf5')
print(snap)  # get info about the snapshot
print(snap.pos['stars'].mean(axis=0))  # get a rough center of mass of the simulation

Updated tutorials coming soon. In the meantime, see https://github.com/stephenpardy/Offsets_Notebooks for some older examples (not all may work with this version).
