I tried with somewhat different parameters so as to make the frb square and it worked. So the issue seems to be with making non-square cuts, or maybe in making the frb from the cut. I wonder if this is a recurrence of issue #1023, but it doesn't look like it. I don't have time at the moment to post my dataset, but I will soon. It is fairly large so I hope that's not a problem..</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Jon</div><br><div class="gmail_quote">On Fri, Mar 10, 2017 at 4:05 PM, <span dir="ltr"><<a href="mailto:yt-users-request@lists.spacepope.org" target="_blank">yt-users-request@lists.<wbr>spacepope.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div id="m_5531975511922015978:191" class="m_5531975511922015978a3s m_5531975511922015978aXjCH m_5531975511922015978m15aba0a525517a43">Date: Fri, 10 Mar 2017 12:14:55 -0800<br>

Hi Jonathan,<br>
<br>
I'm not able to reproduce the behavior you're seeing with a test dataset<br>
(e.g. see <a href="http://paste.yt-project.org/show/7080/" rel="noreferrer" target="_blank">http://paste.yt-project.org/sh<wbr>ow/7080/</a>, this uses a dataset from<br>
<a href="http://yt-project.org/data" rel="noreferrer" target="_blank">yt-project.org/data</a>).<br>
<br>
Is there any chance you can share a dataset that triggers this?<br>
Alternatively, can you reproduce this using one of the test datasets on<br>
<a href="http://yt-project.org/data" rel="noreferrer" target="_blank">yt-project.org/data</a>?<br>
<br>
The yt curldrop might be useful to share a dataset that triggers the issue<br>
you're seeing, see <a href="http://docs.hub.yt" rel="noreferrer" target="_blank">docs.hub.yt</a>. If you're not comfortable sharing the<br>
dataset publicly, feel free to share it with me off-list.<br>
