5.1. prefix.fusion.sorted.bam¶
BAM file containing the chimeric reads supporting gene fusions. Comparing to the orignal BAM file, two additional tags are added to each alignment record: FN (Fusion Name) and SR (Supporting Read)
SR:i:1 : Fusion was supported by split read
SR:i:2 : Fusion was supported by paired reads
SR:I:3 : Fusion was supported by both split read and paired reads.

5.2. prefix.fusion.sorted.bam.bai¶
The index file of prefix.fusion.sorted.bam
5.3. prefix.fusion.bed¶
This is standard BED12 format file. Paired reads are merged into a single BED entry. This file can be uploaded to UCSC genome browser to visualize intra-chromosomal fusions. This is useful to identify the fusion point.
5.4. prefix.fusion.interact.bed¶
This is Interact format file. This file can be uploaded to UCSC genome browser to visualize both intra-chromosomal and inter-chromosomal fusions.
Intra-chromosomal fusions will be visualized as below (Note the two breaking points on ERG gene). Toggle between full display mode and pack/squish display mode help identify the exact breaking point(s).
Inter-chromosomal fusions will be visualized as below. Toggle between full display mode and pack/squish display mode help identify the exact breaking point(s).
5.5. prefix.fusion.summary.txt¶
Report the total number of supporting RNA fragments (split reads + read pairs) for each fusion.
