These are individual preprocessed data (the β weights).Each subject's folder contains ten subfolders, including the β for each frequency band and for defining the functional ROIs (see our paper for more details). In the names of the subfolders, "lh" and "rh" stand for left and right hemispheres. "visStim_lh" and "visStim_rh" comprise the β weights for defining the functional ROIs.To extract β weights of a frequency condition, for example, alpha in the left hemisphere: hdr = load_nifti( 'subj1\Alpha_lh\beta.nii.gz');theBetasOfAlpha = hdr.vol (:, 1, , 2);To extract β weights of the visStim:hdr = load_nifti( 'subj1\visStim\beta.nii.gz');theBetas = hdr.vol (:, 1, , );
