+This tool computes (i) the number of pairs **aligned** reads by overlap classes (in nt) and associated the z-scores,
+and (ii) the ping-pong signal (`Brennecke et al, 2009`_) and associated z-scores.
+
+**Note** that the number of pairs of aligned reads is disctint from the number of pairs of reads
+when these reads can be aligned at multiple positions in the genome. The two values are equal only
+when the analysis is restricted to uniquely mapping reads.
+
 Options set the min and max size of both the query small rna class and the target small rna class, 
 the range over which to compute the signatures, and whether the signatures should be reported at 
 genome-wide level or by item (chromosomes, genes, etc.). For details on computational algorithmes
