The function computes the Latency of MUAes by fitting 5 cumulative Gaussian distribution parameters (mu, sigma, alpha, c, d) following (Roelfsema, Tolboom, Khayat, Neuron 2007), developed for (Ferro, van Kempen, Boyd, Panzeri, Thiele, PNAS 2021).

Analysis-of-MUAe-latency

% COMPUTE LATENCY function written by Demetrio Ferro <demetrio.ferro@upf.edu>
% Based on (Roelfsema, Tolboom, Khayat, Neuron 2007).
% developed for (Ferro, van Kempen, Boyd, Panzeri, Thiele, PNAS 2021)


% The function computes Latency indices base don MUAes fitted by cumulative 
% gaussian function with 5 (degrees of freedom) parameters (mu, sigma, alpha, c, d).
% The best fit is assigned based on Least Squares (LS) of iterative estimation.

% Inputs:
% MuaeData          [NxT]  Multi-channel (N channels) MUAes in time (T points) 
% MuaeTimes         [1xT]  Timestamps of MUAe recordings (T points)
% lsqTimeRes        [1x1]  Resolution of time series for Latency estimation

% Outputs:
% latTimes          [1xN]  Latency indices at t*:={f(t*)=1/3*max(f(t)),t in MuaeTimes}
% lsqCurveTimes     [1x(T*lsqTimeRes)] Timestamps of fitted curves
% lsqFittedCurve    [Nx(T*lsqTimeRes)] Fitted curves at LS parameters
% lsqFittedParam    [Nx5]  LS parameters
% lsqFitErr         [1xN]  LS error of the fit
