[yt-users] constructing cic error on load: "YTOutputNotIdentified"

[Nathan Goldbaum]

Does the file /bigbang/data/AnnaGroup/caterpillar/parent/gL100X10/outputs/snapdir_000/snap_000
exist?

What happens when you try to load it with GadgetHDF5Dataset instead of the
load function?

The load function uses the _is_valid methods that are defined on each of
the Dataset subclasses to determine the appropriate output type - that's
usually the first place to look for things going wrong with loading
datasets.
