Hi Jean-Claude, Unfortunately, this is a known bug. I'm working on improving DM-only support, but for now I think it's somewhat usable. I believe your error can be fixed if, during instantiation of the EnzoStaticOutput, you specify the type of output it is: pf = EnzoStaticOutput(path_to_output, data_style=6) where data_style is the argument that describes the type of data. 5 is normal HDF5, 6 is the "packed" HDF5. You can tell the difference between the two by how the files in the directory are laid out -- do you have one file per processor (packed HDF5) or do you have one file per grid (normal HDF5)? -Matt On Tue, Feb 10, 2009 at 6:43 AM, Jean-Claude Waizmann wrote:

Hi all,

I have problems in using yt with the dm-only output of enzo-1.5. If I run e.g. the hop recipe, than it fails already at:

full_sphere = pf.h.sphere([0.5,0.5,0.5], 1.0)

Using the same script on dm+hydro output works without any problems, so it seems that yt is confused by the output format. Does anyone know how to use yt with the dm-only output.

Thanks, Jean-Claude
