Sorry I've been on a tear with yt lately, but on two machines I've noticed that the hop circles have only been showing up on the upper left quad of the image. Not sure what happened, but I'm just using the standard recipe from the yt docs… -- Eric Hallman Tech-X Corporation hallman@txcorp.com 5621 Arapahoe Ave, Suite A Phone: (720) 254-5833 Boulder, CO 80303 Fax: (303) 448-7756 --
Hi Eric, The HopCircleCallback doesn't account for the fact that you're doing a simulation with periodic boundary conditions. It looks like the halo you're centering on is near a corner of the simulation box, causing only the halos in one quadrant to be plotted. If you're focusing on the most massive halo in the box, it's probably a good idea to recenter the simulation on that halo. If you're unsure how to do that, it's described in the enzo docs as well as in lecture slides from the 2010 enzo workshop and the HIPACC summer school. You can also e-mail enzo-users. Reentering the simulation on the most massive halo has the additional bonus that callback plots like the one you've attached will look correct.

Nathan, ok. Thanks. I didn't realize that hop circles wasn't periodic by nature. I will recenter. Eric On Mar 13, 2012, at 5:31 PM, Nathan Goldbaum wrote:
