I am running an experiment on different subjects of 500 trials per subject. I have 20 subjects and data on each subject has been collected and analysed individually.I will like to add or append the saved mat file for each subject in order to have the group statistics. How do I go about it. Find below how I tried to add the first 4 subjects. Thank you
Data_session=[];
filename=('session.mat')
for j=1:size(data,4)
    a=load('sess1')
    b=load('sess2')
    c=load('sess3')
    d=load('sess4')
    save('session.mat','a','b','c','d')
    save('session.mat','a','b','c','d',-'append')
    
end
