Hi Andrew, Thanks for the bug report; how embarrassing. I have pushed a fix to my repository; it only touches Orion. Casey and I are fixing up some other issues in the Nyx frontend before that gets finished up. I am inclined to leave Maestro and Castro and attempt to unify Boxlib readers rather than salve this wound. This week the workshop is taking a bit of time, but early next week I will take a look at the (admittedly confusing) hierarchy and frontend code and see if I can codify this. The changes to field detection resulted in this. Could you please test it by doing: hg pull -r 736067d72401 http://bitbucket.org/MatthewTurk/yt hg up and then re-running your script? This also includes changes to the FLASH stuff, and I'm waiting on the integration tests to run before I am willing to push it to the main repository. Could you let me know if it works for Orion? -Matt On Wed, Jan 25, 2012 at 12:01 AM, Andrew Myers <atmyers@berkeley.edu> wrote:
Hello All,
It looks like there is a problem with the current stable version of yt that comes up when creating a PlotCollection using Orion datasets. See the script here and the traceback here.
I think the fix is that there needs to be the line
self.field_info = pf.field_info
somewhere in the constructor for OrionHierarchy (around line 120 of yt/frontends/orion/data_structures.py). It looks like a line like this used to be here, but was removed during some code cleanup. If the other Orion users are anything like me, they haven't updated yt in a while and thus haven't noticed the problem.
Glancing at the Nyx, Maestro, and Castro frontends, those look like they might suffer from the same issue, but I don't have any of their data to confirm or deny this.
