FT_SPIKE_WAVEFORM
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_spike_waveform”.
FT_SPIKE_WAVEFORM computes descriptive parameters on waveform (mean and variance), and performs operations like realignment, outlier rejection, invertation, normalization and interpolation (see configurations). Use as [wave] = ft_spike_waveform(cfg, spike) Or [wave, spike] = ft_spike_waveform(cfg, spike) The input SPIKE should be organised as the SPIKE datatype (see FT_DATATYPE_SPIKE) Configurations: cfg.rejectonpeak = 'yes' (default) or 'no': takes away waveforms with too late peak, and no rising AP towards peak of other waveforms cfg.rejectclippedspikes = 'yes' (default) or 'no': removes spikes that saturated the voltage range. cfg.normalize = 'yes' (default) or 'no': normalizes all waveforms to have peak-to-through amp of 2 cfg.interpolate = double integer (default = 1). Increaes the density of samples by a factor cfg.interpolate cfg.align = 'yes' (def). or 'no'. If 'yes', we align all waves to maximum cfg.fsample = sampling frequency of waveform time-axis. Obligatory field. cfg.spikechannel = See FT_CHANNELSELECTION for details. Outputs: Wave.avg = average waveform Wave.time = time of waveform axis Wave.var = variance of waveform Wave.dof = number of spikes contributing to average Spike structure if two outputs are desired: waveform is replaced by interpolated and cleaned waveforms, removing also their associated time-stamps and data.
