[yt-users] Filter halos that can't be calculated virial quantities

[Britton Smith]

Hi Jullian,

Excellent question!  I think the best way to do this without altering the
source code would be to create a filter that checks for the existence of
the profile file before trying to load them.  Below is an example of one I
coded up using the same logic for setting the filenames at the profile
callback.

If you add this to your script and either add the filter after you do the
profiling or before you load the profiles, this may do it.  Let us know if
you have any more questions.
