#230 error getting ParticleMassMsun with particle io

Reported by yt_analysis (last edited )

Imported Ticket

  • Summary: error getting ParticleMassMsun with particle io
  • Component: yt
  • Milestone: 2.0
  • Reporter: britton
  • Owner: mturk
  • Resolution: fixed
  • Status: closed
  • Created: 1259430726000000
  • Description: 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']
