Processing Modules
^^^^^^^^^^^^^^^^^^

Processing modules are objects that group together common analyses done during processing of data.
To standardize the storage of
common analyses, NWB provides the concept of an :py:class:`~pynwb.core.NWBDataInterface`, where the output of
common analyses are represented as objects that extend the :py:class:`~pynwb.core.NWBDataInterface` class.
In most cases, you will not need to interact with the :py:class:`~pynwb.core.NWBDataInterface` class directly.
More commonly, you will be creating instances of classes that extend this class.

Processing modules are objects that group together common analyses done during processing of data. They
often hold data of different processing/analysis data types.
