[yt-users] Slice Plot Gadget Problem

[Jared Coughlin]

Hi Nathan,
Thank you for responding! I tried what you suggested, but still no luck.
I'm still getting the index out of bounds error.  I've copied the traceback
to the paste bin at: http://paste.yt-project.org/show/5001/
I've included how I loaded the snapshot as well as the call to
yt.SlicePlot, in case that helps.  Thank you very much for all the help!
-Jared
