.. warning:: This version of Trinity, which runs on Greenfield_ at the `Pittsburgh Supercomputing Center`_, is a **beta** version. It may not be possible to rerun the same version of this tool, Trinity itself, or its other dependencies (Bowtie, SAMtools) in the future. **When rerunning this tool on the same data, it should, but cannot be guaranteed to reproduce the exact same results to the level of certainty as other Galaxy tools.**

Trinity is a de novo transcript assembler that uses RNA-seq data as input. This tool runs all Trinity_ commands--Inchworm, Chrysalis, and Butterfly--in a single pass.
