New issue 621: Need better documentation on how to use cut regions in the docs https://bitbucket.org/yt_analysis/yt/issue/621/need-better-documentation-on-... Cameron Hummels: There is a small patch on how to do it buried in there: http://yt-project.org/doc/api/generated/yt.data_objects.data_containers.AMRC... But one has to know that it is called a "cut region" (cutting region doesn't bring it up in search), and it would be better to have a full description of it in a narrative format elsewhere so people could find it easier.
