Hi Yuan, I wanted to agree with Matt, but also wanted to apologize for not answering your earlier email yet. I will look over my scripts and let you know what I come up with. Best, John

Hi Yuan,

Can you give a shot with "all_density" instead of "io_density"? This looks like a bug, but that should fix it for now. And, can you file this as a bug?

I have just started using yt3 and would like to display particle densities in a projection plot.

It seems that for Enzo data, I can use ('deposit', 'io_density'). With Flash data, however, dd['deposit', 'io_density'] will give me an error message: KeyError: "Unable to open object (Object 'particle_posy' doesn't exist)"

I have checked and the particles are there. dd['io', 'particle_posy'] does return the particle y positions, so I am confused. Are there other ways of projecting particle densities for Flash data?

Thank you!

Yuan, Can you try the fix from this pull request? https://bitbucket.org/yt_analysis/yt/pull-request/1294/check-for-particle-fi... https://bitbucket.org/yt_analysis/yt/pull-request/1294/check-for-particle-fi... It should fix your issue. If so, just hit approve on the PR. Thanks, John

Hi Matt,

dd['deposit', 'all_density'] gives the same error message. I have reported the bug on bitbucket.

John, no worries! I happened to have tried to make this plot first (and therefore freaked out), but actually everything else with the particles seems to work nicely, haha!

Thanks! Yuan
