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

Reader function for Ricoh/KIT conversion to FIF.

Parameters

input_fnamestr: Path to the sqd file.
mrkNone | 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.
elpNone | 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.
hspNone | 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.
stimlist 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.
stimthreshfloat: The threshold level for accepting voltage changes in KIT trigger channels as a trigger event.
preloadbool or str (default False): Preload data into memory for data manipulation and faster indexing. If True, the data will be preloaded into memory (fast, requires large amount of memory). If preload is a string, preload is the file name of a memory-mapped file which is used to store the data on the hard drive (slower, requires less memory).
stim_code‘binary’ | ‘channel’: How to decode trigger values from stim channels. ‘binary’ read stim channel events as binary code, ‘channel’ encodes channel number.
allow_unknown_formatbool: Force reading old data that is not officially supported. Alternatively, read and re-save the data with the KIT MEG Laboratory application.
standardize_namesbool: If True, standardize MEG and EEG channel names to be "MEG ###" and "EEG ###". If False (default), native channel names in the file will be used when possible.
verbosebool | str | int | None: Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.
