I would like to track individual particles to the subhalo to which they are gravitationally bound. Is there a way to do this? One such useful field would be one for a subhalo, which lists the ParticleIDs for all bound particles - cannot seem to locate anything analogous on the data specifications page.
Any assistance would be much appreciated,
Jason

I think I have answered this; looking at snapshot.py, if I wanted to load all the dark matter particles for Subhalo #3035 for example, I would write:

dm = il.snapshot.loadSubhalo(basePath,135,3035,'dm').
Hi Jason,
That's right, or
dm_ids = il.snapshot.loadSubhalo(basePath,135,3035,'dm','ParticleIDs')
for just the ids.
