+by utilizing off-target reads.  It allows for extracting uniformly distributed
+copy number information, can be used without reference, and can be applied to

+immunoprecipitation and target enrichment on small gene panels.  Thereby,
+CopywriteR constitutes a widely applicable alternative to available copy
+number detection tools.")
