function [dataInFieldtrip, markersInFieldtrip] = prepro_egg_loadData(subj_idx,dataType,irm)
%{

Function to retrieve subject EGG and IRM volume markers recorded inside or
outside the scanner. This function is called by prepro_egg
 
Input:
subj_idx= eg '8','12'
dataType= 'EGG' for electrogastrogram or 'EKG' for electrocardiogram
irm = if 1 will load data used inside the scanner, if 0 will load data from
outside the scanner

Output: Data and markers in fieldtrip format
