+**What it does**
+
+The user selects a SNP table and specifies the columns containing (1)
+chromosome, (2) position, (3) scores (such as an Fst-value for the SNP), (4)
+a percentage or raw score for the "cutoff" and (5) the number of times the
+data should be randomized (only intervals with score exceeding the maximum for
+the randomized data are reported).  If a percentage (e.g. 95%) is specified
+for #3, then that percentile of the scores is used as the cutoff; this may
+not work well if many SNPs have the same score.  The program subtracts the
+cutoff from every score, then finds genomic intervals (i.e., consecutive runs
+of SNPs) whose total score cannot be increased by adding or subtracting one
+or more SNPs at the ends of the interval.
