PPV (positive predictive value) = no. of true positive peaks/no. of total peaks. Sensitivity = no. of detected true positive regions/96. Unique = number of unique regions found. Correlation = correlation coefficient of the spike-in log fold-changes and algorithm-assigned scores for the 47 unique regions.
