NXScore peaks around TSSs. An example of NXScore peaks around the transcriptional start site of genes. Shown above are the NXScores for two neighboring genes on chromosome 21. The figure was prepared by uploading NXScore results as a Custom Track on the UCSC Genome Browser, and taking a snapshot with the Known Genes track.
