msmbuilder.io.preload_tops

msmbuilder.io.preload_tops(meta)

Load all topology files into memory.

This might save some performance compared to re-parsing the topology file for each trajectory you try to load in. Typically, you have far fewer (possibly 1) topologies than trajectories

Parameters:

meta : pd.DataFrame

The DataFrame of metadata with a column named ‘top_fn’

Returns:

tops : dict

Dictionary of md.Topology objects, keyed by “top_fn” values.
