trackpy.PandasHDFStoreBig¶

class trackpy.PandasHDFStoreBig(filename, mode='a', t_column='frame', **kwargs)¶

Like PandasHDFStore, but keeps a cache of frame numbers.

This can give a large performance boost when a file contains thousands of frames.

If a file was made in PandasHDFStore, opening it with this class and then closing it will add a cache (if mode != ‘r’).

Any additional keyword arguments to the constructor are passed to pandas.HDFStore().
