Off-list JC sent me his data, and I was able to track it down to an off-by-one error for field detection in Enzo. Should be fixed now! On Mon, Mar 26, 2012 at 5:28 AM, Matthew Turk <matthewturk@gmail.com> wrote:

Hi JC,

Looks like a problem with detecting the fields.  If you send me info off-list on how to replicate this, I can see where exactly the field detection is going awry, and how to fix it.

Hi everyone,

I get an error when executing the simple script below:

------------------------------------------------------------------------------ from yt.mods import * output = 'DD0010/data0010' pf = load(output) region = pf.h.region([0.5,0.5,0.5],[0.0,0.0,0.0],[1.0,1.0,1.0]) ------------------------------------------------------------------------------ I have pasted the output there: http://paste.yt-project.org/show/awqlzVK7mAhtiIVihFfC/ I think the problem is that my simulation has only 2 particles (no gas) and both particles are in subgrids so the root grid is empty:

------------------------------------------------------------------------------ [19:46:54] Obiwan:$ h5ls DD0010/data0010.cpu0000 Grid00000001 Group Grid00000002             Group Metadata                 Group [19:47:09] Obiwan:$ h5ls DD0010/data0010.cpu0000/Grid00000001 [19:47:15] Obiwan:$ h5ls DD0010/data0010.cpu0000/Grid00000002 particle_index Dataset {2} particle_mass            Dataset {2} particle_position_x Dataset {2} particle_position_y      Dataset {2} particle_position_z Dataset {2} particle_type            Dataset {2} particle_velocity_x Dataset {2} particle_velocity_y      Dataset {2} particle_velocity_z Dataset {2} ------------------------------------------------------------------------------ I would really appreciate if someone could help me to fix this. Thanks a lot,

JC
