+**What it does**
+
+The users selects a set of data generated by the Galaxy tool to "prepare
+to look for population structure", and specifies a number, K, of ancestral
+populations.  The tool estimates the proportion of each individual's ancestry
+coming from each ancestral population.  The proportions are shown both as
+numbers and graphically.
