pop_importegimat#

pop_importegimat(filename, srate=None, latpoint0=0.0, data_field='Session', *, fileloc='auto', return_com=False)#

Import a segmented or continuous EGI Net Station MATLAB file.

Net Station segmented exports store one channel-by-sample matrix per <condition>_Segment<number> variable. They become trials ordered first by condition name and then by segment number, with one event per trial. Continuous exports are read from data_field ("Session" by default). An embedded scalar samplingRate takes precedence over srate.

Parameters:

  • filename (str | Path) – MATLAB file exported by EGI Net Station.

  • srate (float | None) – Sampling rate in Hz when the file does not contain samplingRate.

  • latpoint0 (float) – Milliseconds from the start of each segment to time zero.

  • data_field (str) – Continuous-data variable name or MATLAB-compatible prefix.

  • fileloc (str | Path | None) – EGI montage filename. "auto" selects the packaged montage from the imported channel count; an empty string skips locations.

  • return_com (bool) – Return (EEG, command) when true.

Returns:

An EEG dictionary, optionally paired with its replayable history command.

Return type:

dict[str, Any] | tuple[dict[str, Any], str]
