% < 0.1, percentage of correlations with value smaller than 0.1; % 0.1 to 0.5, percentage of correlations in the interval 0.1 to 0.5; % > 0.5, percentage of correlations with values greater than 0.5. Categories are ordered according to decreasing minimal correlation in the group. N, number of correlations between peaks in the category: N = (number of peaks in the category2 - number of peaks in the category)/2).
