Hi Anna, One thing that is not the most common with Orion data is that yt requires the inputs file. Usually when this error shows up, the inputs file isn't around. There's an example here: http://yt-project.org/docs/2.3/analyzing/loading_data.html?highlight=orion#o... If you do have the inputs file and it still doesn't work, ping us back and we can run some diagnostics. Best, Matt PS I think this is your first email to the list -- welcome to yt! :) On Mon, Jan 9, 2012 at 8:58 PM, Anna Rosen <rosen@ucolick.org> wrote:

Hi,

I am new to yt and orion and I am trying to read in data from an example simulation which includes sink particles (uniformcloud). When I load the plot  file into yt with the command I get an error saying that yt is unable to read it. Please see the output below.

In [1]: from yt.mods import *

In [2]: pf=load('plt00050') yt : [ERROR    ] 2012-01-09 17:55:23,591 Couldn't figure out output type for plt00050

Thanks for your help!
