mne.io.read_raw_kit(input_fname, mrk=None, elp=None, hsp=None, stim='>', slope='-', stimthresh=1, preload=False, stim_code='binary', verbose=None)

Reader function for KIT conversion to FIF

Parameters:

input_fname : str

Path to the sqd file.

mrk : None | str | array_like, shape = (5, 3) | list of str or array_like

Marker points representing the location of the marker coils with respect to the MEG Sensors, or path to a marker file. If list, all of the markers will be averaged together.

elp : None | str | array_like, shape = (8, 3)

Digitizer points representing the location of the fiducials and the marker coils with respect to the digitized head shape, or path to a file containing these points.

hsp : None | str | array, shape = (n_points, 3)

Digitizer head shape points, or path to head shape file. If more than 10`000 points are in the head shape, they are automatically decimated.

stim : list of int | ‘<’ | ‘>’

Channel-value correspondence when converting KIT trigger channels to a Neuromag-style stim channel. For ‘<’, the largest values are assigned to the first channel (default). For ‘>’, the largest values are assigned to the last channel. Can also be specified as a list of trigger channel indexes.

slope : ‘+’ | ‘-‘

How to interpret values on KIT trigger channels when synthesizing a Neuromag-style stim channel. With ‘+’, a positive slope (low-to-high) is interpreted as an event. With ‘-‘, a negative slope (high-to-low) is interpreted as an event.

stimthresh : float

The threshold level for accepting voltage changes in KIT trigger channels as a trigger event.

preload : bool

If True, all data are loaded at initialization. If False, data are not read until save.

stim_code : ‘binary’ | ‘channel’

How to decode trigger values from stim channels. ‘binary’ read stim channel events as binary code, ‘channel’ encodes channel number.

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose).

Returns:

raw : Instance of RawKIT

A Raw object containing KIT data.
