New issue 935: Particle Density Projection for Flash Data https://bitbucket.org/yt_analysis/yt/issue/935/particle-density-projection-f... yl2501: I am trying to make a particle density projection plot with Flash data. dd['deposit', 'io_density'] gives an error message: KeyError: "Unable to open object (Object 'particle_posy' doesn't exist)" dd['deposit', 'all_density'] gives the same error message.
