Hi All,
Is it possible to deposit the particles from a gadget data set onto a uniform grid in yt? Or, could it be possible to trick the octree deposition into doing it by forcing no refinements, but some sort of native grid resolution?
thanks, desika

Yes, you're looking for an arbitrary_grid:

Hi Desika,
Yup, this can be done reasonably easily using either the .arbitrary_grid object (which was designed for this) or the interface to the arbitrary grid that's in the development version, which is ds.r[ ... ] where the ... is some combination of bounds and steps.

Hi All,
A follow-up question: In using arbitrary_grid (but with enzo data), how does one then extract a field of an arbitrary_grid? I tried arbgrid["density"] as I have done with a smoothed_covering_grid object, but it does not work (here is the traceback http://pastebin.com/afgcgpp0 I got).
Thanks, Carla

Hi Carla,
This functionality was recently implemented and is in the development version, but not yet in the stable. We're hoping for a release very shortly, but you can also try the dev version if you'd like!
