## Overview

This super-track combines related tracks of genome-wide Transcriptome Phase 3 data generated by Affymetrix. There are four member tracks:

- Affymetrix Transcriptome Phase 3 Long RNA Fragments - the transcribed fragments (transfrags) representing long RNAs.
- Affymetrix Transcriptome Phase 3 Long RNA Signal - the signal level estimated for each mapped probe position after hybridization with long RNA samples.
- Affymetrix Transcriptome Phase 3 Short RNA Fragments - the transcribed fragments (transfrags) representing short RNAs.
- Affymetrix Transcriptome Phase 3 Short RNA Signal - the signal level estimated for each mapped probe position after hybridization with short RNA samples.
