pyneuroml.lems.load_sim_data_from_lems_file(lems_file_name: str, base_dir: str = '.', get_events: bool = True, get_traces: bool = True) → Tuple[Dict, Dict] | Dict#

Load simulation outputs using the LEMS simulation file

Added in version 1.2.2.

Parameters:

  • lems_file_name (str) – name of LEMS file that was used to generate the data

  • base_dir (str) – directory to run in

Returns:

if both get_events and get_traces are selected, a tuple with two dictionaries, one for traces, one for events, is returned.

Otherwise one dictionary for whichever was selected.

The events dictionary has the following format:

{
    '<value of select attribute>': [<events>]
}

The traces dictionary has the following format:

{
    't': [<values>],
    'col 1': [<values>]
}

Raises:

  • ValueError – if neither traces nor events are selected for loading

  • ValueError – if no traces are found

  • ValueError – if no events are found

pyneuroml.lems.safe_variable(quantity)#

Make a variable safe.

It replaces [, ], /, . with _.

Parameters:

  • quantity – quantitiy to make safe

  • quantity – str

Returns:

quantity after it was made safe

Return type:

str
