Hello!!
I have a main folder (with this directory D:\ABIDEdataset\Outputs\dparsf\nofilt_noglobal\rois_aal) and 16 subfolders (Caltech, KKI, Leuven, Stanford,etc..) in it, with each subfolder containing several *mat files within them. I want to create a loop that goes through all the files coming from all the subfolders and use each file for then perform some calculations.
Thanks in advance!

You can use a filedatastore with a reader function that loads the appropriate variables from the .mat files.
Or you can use dir with ** wildcard:
dinfo = dir('D:\ABIDEdataset\Outputs\dparsf\nofilt_noglobal\rois_aal\**\*.mat');
filenames = fullfile({dinfo.folder}, {dinfo.name});
numfiles = length(filenames);
for K = 1 : numfiles
thisfile = filenames{K};
do something with thisfile
end

It already does that in practice. Not really guaranteed, though. You could guarantee it by sort(filenames) before you loop.
