+NAME
+    rsem-prepare-reference
+
+SYNOPSIS
+    rsem-prepare-reference [options] reference_fasta_file(s) reference_name
+
+DESCRIPTION
+    The rsem-prepare-reference program extracts/preprocesses the reference sequences and builds Bowtie indices using default parameters. 
+    This program is used in conjunction with the 'rsem-calculate-expression' program.
