[yt-users] Flash Particle files and DatasetSeries

[Nathan Goldbaum]

Hi Alex,

Looking at the DatasetSeries code, I don't think there's an easy way to do
this right now.

It would work if you could use the setup_function argument when you create
the DatasetSeries, but I don't think there's a way to associate a particle
filename with a dataset *after* it's been loaded.

I see two ways forward here:

1. Make keyword arguments passed to the DatasetSeries initializer get
passed to `load` when DatasetSeries invokes loads each individual dataset
internally.

2. Make it possible to associate a particle file with a FLASH dataset after
the dataset has been loaded.

I think the first option would be more generally useful, but option 2 might
be useful for some FLASH users as well.

Would you be interested in trying to get this to work? If not I can file an
issue and try to get to it sometime soon...

-Nathan
