+Uses pRESTO SplitSeq.py group to partition a file of sequences into two files. The input file is split based on a numeric
+annotation field to yield one file which contains all sequences with the field value less than the provided threshold and
+a second file with all sequences with the field value greater than or equal to the threshold.
+
+See the `pRESTO online help <@PRESTO_URL_BASE@/SplitSeq.html>`_ for more information.
