[yt-users] Halo Finding Problems

[Brian Crosby]

Hi All,

I've been trying to find and plot some halos from an Enzo simulation on Ranger and got this error today:

Traceback (most recent call last):
  File "projections.py", line 4, in <module>
    halos = HaloFinder(pf, padding=0.03)
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/HaloFinding.py", line 1786, in __init__
    self._join_halolists()
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/HaloFinding.py", line 1382, in _join_halolists
    self._groups.sort(haloCmp)
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/HaloFinding.py", line 1381, in haloCmp
    return cmp(h1.center_of_mass()[0],h2.center_of_mass()[0])
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/ParallelTools.py", line 133, in single_proc_results
    retval = func(self, *args, **kwargs)
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/HaloFinding.py", line 94, in center_of_mass
    c_vec = self.maximum_density_location() - na.array([0.5,0.5,0.5])
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/ParallelTools.py", line 130, in single_proc_results
    return func(self, *args, **kwargs)
  File "/share/home/01450/bcrosby/yt-x86_64/src/yt-1.7-svn/yt/lagos/HaloFinding.py", line 125, in maximum_density_location
    self._max_dens[self.id][1],
KeyError: 604

Does anyone know what's going on here?

Thanks,
Brian
