rdpat.m

A MATLAB tool for analysis of Transient Otoacoustic Emission signals

function [Files,Names,Ear,Date,dtaPath]=rdpat(dire);

%RDPAT reads patient information of ILO88 dta-files in directory dire
%       [Files,Names,Ear,Date,Path]=rdpat(dire)
%   in: dire    directory to read from (default gives uigetfile)
%
%  out: Files   names of all dta-files (string matrix)
%       Names   names of patients in files (string matrix)
%       Ear     which ear was measured, Left or Right (string matrix)
%       Date    dates of measurements (string matrix)
%       dtaPath    path of file location
