Hi Matt,

The change you suggested solved the problem of
ad['DarkMatter', 'particle_mass']
and
ad['CenOstriker', 'particle_mass']

However, when I do:
ad['all', 'particle_mass']
I get the following:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/britton/Documents/work/yt/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 189, in __getitem__
    self.get_data(f)

    rv[field_f][my_ind:my_ind + vals.shape[0],...] = vals
ValueError: could not broadcast input array from shape (4851) into shape (4361)

Additionally, if I do:
ad['io', 'particle_mass']
I get this (which I got before this change as well):
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/britton/Documents/work/yt/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 183, in __getitem__

    raise YTFieldTypeNotFound(ftype)
yt.utilities.exceptions.YTFieldTypeNotFound: Could not find field 'io'.

Thanks, Matt!  I'll check this now and do so it if looks like it's working right.

Hey Britton,

I just dug into it briefly, and it looks like the particle types for
active particles are not being "set up" the way they ought to be.  I
think the issue is that particle_types_raw was not being set
correctly.  Adding this line:

        self.particle_types_raw = self.particle_types

on line 855 of enzo/data_structures.py fixed it for me.  Can you
double-check the values, compare "io" to "DarkMatter" (they should be
identical) and if that looks good to you, submit a PR?
