[yt-users] reading RAMSES files - missing cosmological_simulation flag?

[Rok Roskar]

hi there,

trying to read a RAMSES output from a cosmological zoom simulation, I
get the following perplexing error: 

>>> from yt.mods import *
>>> sim = load("output_00422/info_00422.txt")
output_00422/amr_00422.out00001
yt : [INFO     ] 2011-08-05 15:13:45,236 Parameters: current_time
= -2.10180018413e+16
yt : [INFO     ] 2011-08-05 15:13:45,237 Parameters: domain_dimensions
= [2 2 2]
yt : [INFO     ] 2011-08-05 15:13:45,237 Parameters: domain_left_edge
= [ 0.  0.  0.]
yt : [INFO     ] 2011-08-05 15:13:45,238 Parameters: domain_right_edge
= [ 1.  1.  1.]
yt : [ERROR    ] 2011-08-05 15:13:45,238 Missing cosmological_simulation
in parameter file definition!


this clearly is a cosmological simulation with the relevant parameters
specified in the info*.txt file - is something else needed? 

Thanks,

Rok
