Detailed Description

Helper class for the burst_creator node.

Calculates baselines and spike thresholds for each of the 60 channels in a multi-electrode array.

Definition at line 22 of file buffer_spike_detector.h.

Constructor & Destructor Documentation

BufferSpikeDetector::BufferSpikeDetector ( )

Sets values to their initial states.

Definition at line 14 of file buffer_spike_detector.cpp.

void BufferSpikeDetector::add ( const neuro_recv::dish_state & d )

Adds a dish state to the buffer.

Parameters:

d	the dish state to be added

Definition at line 44 of file buffer_spike_detector.cpp.

void BufferSpikeDetector::calculate ( ) [private]

Calculates values for each channel.

The values calculated are: baseline, variance, standard deviation, threshold. This method is not called until the buffer is full.

Definition at line 71 of file buffer_spike_detector.cpp.

double BufferSpikeDetector::getBaseline ( int index ) [inline]

Definition at line 28 of file buffer_spike_detector.h.

burst_calc::ranges BufferSpikeDetector::getRanges ( )

Returns a range object with values for each channel.

The values stored are: baseline, threshold, min voltage, max voltage.

Definition at line 92 of file buffer_spike_detector.cpp.

double BufferSpikeDetector::getThreshold ( int index ) [inline]

Definition at line 29 of file buffer_spike_detector.h.

void BufferSpikeDetector::init	(	int	buffer_size,
		double	stdev_mult
	)

Gives the object values needed for later calculations.

Parameters:

buffer_size	the number of dish states used to calculate baselines and thresholds
stdev_mult	the standard deviation multiplier used when calculating thresholds

Definition at line 34 of file buffer_spike_detector.cpp.

bool BufferSpikeDetector::isBuffered ( ) [inline]

Definition at line 30 of file buffer_spike_detector.h.
