SpikeFeatures

Detect spikes in a TimeSeries data stream and emits a column data type packet containing all selected features for the decoding.

possible features available are timestamp, amplitude, slope, channel index, channel depth. These features are disabled by default and need to be enabled in the graph options.

Output port

port name	data type	slots	description
data	ColumnData <double>	1-385	data packet containing spikes with the selected features. The packet is expandable - aka nsamples is resized for the real number of spikes.

Options

port name	data type	default	description
threshold	double	70.0	Spike detection threshold in data units.
invert signal	bool	True	Invert signal before spike detection.
peak lifetime	unsigned int	1 samples	Peak life time in samples
features	vector of string	empty, required option	list of features to use in output
channelmap	map of string / double	empty, mandatory when the depth feature is activated	mapping between channel number and channel depth
