Hi all, I'm working with particle filters for the first time and I'm unclear on the role of the filtered_type keyword. For example, in the following script: http://paste.yt-project.org/show/4099/ I define filters that should catch every single particle in an Enzo-3.0 dataset. My understanding of the filtered_type keyword is that is preselected which type of particles to pass through the filter. In this dataset, I have the following particles: Type Number DarkMatter 32768 CenOstriker 10543 Total 43311 So, my understanding is that print ad['finest_all', 'particle_mass'].size should print 43311 and print ad['finest_all', 'particle_mass'].size should print 32768. However, they both print 43311. Is this a bug or am I not understanding what filtered_type is supposed to do? Britton

Can you upload the dataset -- which I think will be a good, representative example of Enzo-3.0 -- to the data directory? -Matt

I modified your example slightly: http://paste.yt-project.org/show/4100/ and got output that looks right to me. CenOstriker 824 DarkMatter 32765 all 33589 finest 32765 finest_all 33589 finest 32765 finest_all 33589 I'm on 500acd8e6551; which one are you on? (If it's the units refactor, that has not been updated yet to the latest tip of yt-3.0.) -Matt

Hi Matt and Devin, I can't say what happened, but both Matt's and my script are now giving the output I expected. Matt, I was on the same changeset as you. The only thing that has changed is the seat under me (office to home) and perhaps a return to sanity from a brief vacation. Sorry for the noise, everyone.
