TopHat-SE

Community rating: ?????

TopHat (for single end reads) is a fast splice junction mapper for RNA-Seq reads. It aligns RNA-Seq reads to mammalian-sized genomes using the ultra high-throughput short read aligner Bowtie, and then identifies splice junctions between exons.

Quick Start

  • To use TopHat-SE, import your data in fastq format.
  • Resources: http://tophat.cbcb.umd.edu/
    Version in DE makes use of a wrapper script developed by Sheldon McKay.
