Hi everyone,

I'm new to yt and am using the latest version (3.0), with support for TIPSY output.  I'm having issues creating temperature slices.  The data I am using is a periodic box, not equal length in all dimensions.

My script goes like this:

pf = load(fn, parameter_file=paramfile)
pf.field_list
slc = SlicePlot(pf,'z','temperature',width=(1,'kpc'),center=[0,0,0])

When I try to create the slice, I receive the following error:
In [9]: slc = SlicePlot(pf,'z','temperature',width=(1,'kpc'),center=[0,0,0])

error: data is of incorrect type (wanted 1D float)

I have no idea what could be causing this, any ideas on how to solve this error?
