+in a single-cell dataset.  Importantly, \"informative\" is decided based on
+how well a gene's variation agrees with some cell metric---some similarity
+mapping between cells.  Genes which are informative are those whose expression
+varies in similar way among cells which are nearby in the given metric.")
