Hi Britton,
ParticleIO is still kind of new, I guess! I think there's something wrong with the dependency calculator in this case -- something about the hackery around particle_mass and "particle mass". There are two ways forward for this that I think we need to think about -- global field name translations, and fixing the field dependencies. If you fill out a ticket for this problem, I'll examine it this coming week...

Hey everyone,
The following error pertains to the yt branch of the hg repo.
I'm getting a particle io error when using the various yt halo finders in parallel. It doesn't appear to have anything to do with the halo finders, but I don't know what else uses ParticleIO.py. This only happens when running in parallel.

I checked the contents of to_add, and it was a list with two items (hence the exception): ['particle_mass', 'particle_mass']
I was able to get around this by removing non-unique entries in to_add, but I don't think that really fixes the underlying problem. Anyone have any ideas?

Britton
