Hi there,
I have a sample of muscle contractions from 12 different muscles for 10 subjects. All time normalized (100AU). I want to apply the following calculation to each one of them without having to copy paste the code:
Max = max(muscle); %muscle has to be specified by hand
threshold = 0.25*Max;
indices = find(abs(muscle)>2);
muscle(indices) = NaN;
So basically I am finding the maxEMG activity of the contraction, taking 25% as a cuttoff threshold and eliminating any value below that threshold. And I would like that to be repeated for each muscle, but I can't figure out how to use a loop whithout the name of the muscle being the same over and over.
Any ideas?
Thanks in advance!

max(muscles,[],2)

I'm guessing that the 10 subjects data is in 10 different data files. You need to read in each one, and process it, which might mean processing each of the 12 signals for that subject. So you need to loop over all files like is explained in the FAQ: Click Here
