 Short vs long range contacts
 ============================
 
-Computes the ratio of short vs. long range contacts on the given matrices and makes, if two or more matrices are present a differential test between the matrices.
+hicPlotSVL computes the ratio between short range and long range contacts per chromosome independently. Per sample one box plot is created and, 
+if more than one sample is given, the computed ratios are assumed to be one distribution and a Wilcoxon rank-sum test under H0 'distributions are equal' 
+is computed. All used data is written to a third raw data file.
+
+The distance to distinct short and long range contacts can be set via the –distance parameter; for short range the sum for all contacts smaller or equal this distance are computed, for long range contacts all contacts greater this distance.
+
+
