FusionInspector is a component of the Trinity Cancer Transcriptome Analysis Toolkit (CTAT). FusionInspector assists in fusion transcript discovery by performing a supervised analysis of fusion predictions, attempting to recover and re-score evidence for such predictions. Please read more here_.

**To Visualize Output**

After completion, results can be visualized in galaxy. Click on the output json file name in the history (on the right). A more detailed view of that file will be shown. Click on the button in the middle that looks like a bar chart. The visualization should now open for you to explore results.

**There are several output files for the CTAT Fusion Inspector Pipeline. Files of interest include:**

1. **fidx**: Finspector_fasta index file (required for visualization).

2. **cytoBand**: Cytogenetic information for hg19.

3. **finspector_fasta**: The candidate fusion-gene contigs.

4. **finspector_bed**: The reference gene structure annotations for fusion partners.

5. **FusionJuncSpan**: Tabular details on junction reads and spanning reads.

6. **junction_bed**: Alignments of the breakpoint-junction supporting reads.

7. **junction_bam**: Alignments of the breakpoint-junction supporting reads.

8. **spanning_bam**: Alignments of the breakpoint-spanning paired-end reads.

9. **spanning_bed**: Alignments of the breakpoint-spanning paired-end reads.

10. **trinity_bed**: Fusion-guided Trinity assembly.

11. **fusion_predictions.final**: All fusion evidence described.

12. **fusion_predictions_abridged**: encompasses all information in fusion_predictions.final excluding the names of the reads.

13. **fusion_json**: A logistical file that enables the visualization.
