+mutually nearest neighbors, as well as several efficient variants of linear
+regression of the log-expression values.  Functions are also provided to
+perform global rescaling to remove differences in depth between batches, and
+to perform a principal components analysis that is robust to differences in
+the numbers of cells across batches.")
