DISCASM aims to extract reads that map to reference genomes in a discordant fashion and optionally include reads that do not map to the genome at all, and perform a de novo transcriptome assembly of these reads. DISCASM relies on the output from STAR (as run via STAR-Fusion), and supports de novo transcriptome assembly using Trinity or Oases. - https://github.com/DISCASM/DISCASM/wiki
