**Cuffmerge Overview**

Cuffmerge is part of Cufflinks_. Please cite: Trapnell C, Williams BA, Pertea G, Mortazavi AM, Kwan G, van Baren MJ, Salzberg SL, Wold B, Pachter L. Transcript assembly and abundance estimation from RNA-Seq reveals thousands of new transcripts and switching among isoforms. Nature Biotechnology doi:10.1038/nbt.1621

**Know what you are doing**

.. class:: warningmark

There is no such thing (yet) as an automated gearshift in expression analysis. It is all like stick-shift driving in San Francisco. In other words, running this tool with default parameters will probably not give you meaningful results. A way to deal with this is to **understand** the parameters by carefully reading the `documentation`__ and experimenting. Fortunately, Galaxy makes experimenting easy.

**Input format**

Cuffmerge takes Cufflinks' GTF output as input, and optionally can take a "reference" annotation (such as from Ensembl_)

.. _Ensembl: http://www.ensembl.org

**Outputs**

Cuffmerge produces the following output files:

Merged transcripts file:

Cuffmerge produces a GTF file that contains an assembly that merges together the input assemblies.
