+percentage and produce copy number plots displaying absolute copy numbers.  For
+this it uses segmented data from the @code{QDNAseq} package, which in turn uses
+a number of dependencies to turn mapped reads into segmented data.  @code{ACE}
+will run @code{QDNAseq} or use its output rds-file of segmented data.  It will
+subsequently run through all samples in the object(s), for which it will create
+individual subdirectories.  For each sample, it will calculate how well the
+segments fit (the relative error) to integer copy numbers for each percentage
+of @dfn{tumor cells} (cells with divergent segments).")
