evalDetectionSimulated

PURPOSE

evaluates a spike detection method for a particular noise level and extraction threshold of the simulated data.

SYNOPSIS

function [TP,FP,misses, nrSpikesTotal, nrSpikesFound, spikeWaveforms, hits, spikeTimestamps, alignErrors] = evalDetectionSimulated( simNr, levelNr, params )

DESCRIPTION

evaluates a spike detection method for a particular noise level and extraction threshold of the simulated data.

returns:
TP: true positives rate
FP: false positives rate
misses: how many were not found
spikeWaveforms/spikeTimestamps: all detected waveforms and their time of occurence
hits: which of the detected waveforms are hits (TPs)
alignErrors: time estimation errors for all hits

CROSS-REFERENCE INFORMATION

This function calls:

detectArtificialSpikes detect spikes from simulated spiketrain
evalSimulatedAlignPerf spiketimes is ground truth (from simulation)
evalSimulatedPerfDetection determines whether detected spikes are real (true positives) or not.
loadSimulationFiles script. loads the requested simulation files into the current workspace.

This function is called by:

calcDetectionROC_perLevel loops over extraction thresholds; all other values are constant.
