Hi Jason,<div><br></div><div>Unfortunately no.

fixing it will require a modification to the cut_region implementation

would like to generate a compound cut region for a FLASH simulation,
but the output I'm getting is odd. I've pasted my simple script here:<br><br><a href="http://paste.yt-project.org/show/6839/" target="_blank">http://paste.yt-project.org/sh<wbr>ow/6839/</a><br><br></div>It
loads a simulation file, creates a compound cut_region (1e4 K < T
< 1e6 K), and applies it to a slice plot. The resulting image is
banded, as you can see by the attached plots. Am I missing something, or
is this a problem related to yt?<br><br></div>FYI, I get the same
behavior when I use a projection plot or only one of the conditionals
(e.g. T < 1e6 K). I've tried both the stock 3.3.1 version, as well as
the self-contained development version that I installed earlier this
afternoon using install_script.sh. Let me know if any other info is
useful.<br><br></div>Cheers,<br></div>Jason<br><br></div></div></div></div>
