Hi Brian, I see the problem. The argument list for the superclass of region takes a different set of arguments that what is being passed in, so one was being interpreted as the field_parameters keyword arg. I have this fixed and will issue a PR now. Britton On Tue, Aug 19, 2014 at 11:36 AM, Brian O'Shea <bwoshea@gmail.com> wrote:
Hi Britton,
That's basically what I'm doing - I was already using ds.region. When I call ds.region() with these inputs:
ad = ds.region((ds.domain_right_edge + ds.domain_left_edge)/2., ds.domain_left_edge, ds.domain_right_edge,field_parameters = {'omega_baryon':0.046} )
(so, modifying ds.region in the way you suggested, though it's functionally equivalent to what I was doing), I get:
--------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-5-6daee9cdd9b5> in <module>() ----> 1 ad = ds.region((ds.domain_right_edge + ds.domain_left_edge)/2., ds.domain_left_edge, ds.domain_right_edge,field_parameters = {'omega_baryon':0.046} )

Am I doing something wrong with how I use field_parameters in this circumstance?
Thanks, Brian

HI Brian,
ds.all_data is a just a wrapper around ds.region that uses ds.domain_left_edge and ds.domain_right_edge. Looking at the source, I can see that it wasn't set up to accept any additional keyword arguments and pass them to region. This can be fixed easily in yt/data_objects/static_output.py (line 575), but in the mean time, you can just replace your ds.all_data call with: ds.region((ds.domain_right_edge + ds.domain_left_edge)/2., ds.domain_left_edge, ds.domain_right_edge) and add your field_parameters keyword there.

Now, followup question: I am also attempting to create a 2D phase
plot of the same quantity (baryon_overdensity vs. temperature), and yt.PhasePlot does not seem to take the field_parameters dictionary, and neither does yt.create_profile. Should I try another avenue to create a phase plot?
Nope, you can supply it to your data source when you create it. They all take the same field_parameters argument.
Hmm. So when I tried that, using:
ad = ds.region(center=[0.5,0.5,0.5],left_edge=[0,0,0],right_edge=[1,1,1],field_parameters = {'omega_baryon':0.046})
(as ds.all_data() does not accept any additional arguments), I get this error:

Is that expected behavior, or do I misunderstand what you're saying?
