+**Function**
+
+Get RT Stop Counts derives the RT stop counts on each nucleotide of each transcript in the reference transcriptome based on a mapped file (.bam), typically the output from the Iterative Mapping module.
+
+-----
+
+**Input**:
+
+* 1. A mapped (.bam) file from Bowtie (or any other mapping program)
+* 2. Reference library sequences (fasta) used to map the reads to
+
+-----
+
+**Output**:
+
+A text file with reverse transcription stop counts mapped to each nucleotide (RTSC file)
