Hello there,

I am acessing the file for some sounds file for stimulus. I play them by randoming each trail. However, for analysis purpose, I'd like to know which sound was played as well. Is there a way to do that? Here is what I have for this

%StartofExperiment%
Sounds='C:\Users\Desktop\data';
fil = fullfile(Sounds,'*.wav');
d = dir(fil);
fnames={d.name};
number_of_trials=numel(d);
shuffleOrder = randperm(number_of_trials);
