Mrsimulator IO

mrsimulator.save(filename: str, simulator: mrsimulator.simulator.Simulator, signal_processors: Optional[List] = None, application: Optional[Dict] = None, with_units: bool = True)

Serialize the Simulator, list of SignalProcessor, and an application dict to a file. Creates a Mrsimulator object and calls save.

Parameters

  • filename (str) – The data is serialized to this file.

  • sim – Simulator object.

  • signal_processors – A list of PostSimulator objects corresponding to the methods in the Simulator object. Default is None.

  • application – Dictionary holding metadata to serialize in the file. The dictionary will be held in the application key.

  • with_units (bool) – If true, physical quantities are represented as string with units. The default is True.

mrsimulator.dict(simulator: mrsimulator.simulator.Simulator, signal_processors: Optional[List] = None, application: Optional[Dict] = None, with_units: bool = True)

Export the Simulator, list of SignalProcessor, and an application dict to a python dictionary. Creates a Mrsimulator object with given arguments and calls json from the Mrsimulator object.

Parameters

  • sim – Simulator object.

  • signal_processors – A list of PostSimulator objects corresponding to the methods in the Simulator object. Default is None.

  • application – Dictionary holding metadata to serialize in the dict. The dictionary will be held under the application key.

  • with_units (bool) – If true, physical quantities are represented as string with units. The default is True.

Returns

Python dictionary

mrsimulator.load(filename: str, parse_units: bool = True)

Load Simulator object, list of SignalProcessor objects and metadata from a JSON searalized file of a Mrsimulator object.

Parameters

  • filename (str) – The location to the .mrsim file.

  • parse_units (bool) – If true, parse the dictionary for units. The default is True.

Returns

Simulator, List[SignalProcessor], Dict.

Return type

Ordered List

mrsimulator.parse(py_dict, parse_units: bool = True)

Parse a dictionary object to the respective Simulator object, list of SignalProcessor objects, and the metadata dictionary. If no signal processors are provided a list of default SignalProcessor objects with length equal to number of methods will be returned.

Parameters

  • py_dict (Dict) – Python dictionary representation of a Mrsimulator object.

  • parse_units (bool) – If true, parse the dictionary for units. Default is True.

Returns

Simulator, List[SignalProcessor], Dict.

Return type

Ordered List

mrsimulator.update_old_file_struct(oldfile: str, newfile: Optional[str] = None)

Convert an old mrsim file where Simulator object keywords existed at the root level along with other seralized attributes to a structure where each object exists under its own keyword. A dictionary representing the new Mrsimulator object is returned. Will write a new mrsim file if newfile arg is provided.

Parameters

  • oldfile (str) – String of path to mrsim file with old structure

  • newfile (str) – Will write new mrsim file to path represented by newfile if given

Returns

Dictionary representation of Mrsimulator object with new structure

Return type

Dict
