Rayas
Discovery of templated insertion threads and somatic retrocopy insertions
Installing rayas
Rayas is available as a statically linked binary, a singularity container (SIF file) or as a docker container. You can also build Rayas from source using a recursive clone and make. Rayas depends on HTSlib and Boost.
git clone --recursive https://github.com/tobiasrausch/rayas.git
cd rayas/
make all
Running rayas
Rayas was designed for paired-end or single-end matched tumor-normal data. It can be used with short reads, for long reads please use lorax.
rayas call -g <genome.fa> -m <control.bam> <tumor.bam>
Simple graph visualization
You can convert the output into a dot graph. Each component represents one templated insertion cluster. Nodes are genomic segments and edges represent the cancer genome structure with edge weights equalling the sequencing read support.
cut -f 4,9 out.bed | sed -e '1s/^/graph {\n/' | sed -e '$a}' > out.dot
dot -Tpdf out.dot -o out.pdf
Somatic retrocopy insertions
For somatic retrocopy insertions, the distance between exons tends to be smaller than the default cutoff of 10kbp. To detect clusters involving retrocopies you have to lower the segment distance threshold:
rayas call -e 1000 -g <genome.fa> -m <control.bam> <tumor.bam>
To catch smaller exons, you may also want to adjust the minimal size:
rayas call -d 5 -i 50 -e 1000 -g <genome.fa> -m <control.bam> <tumor.bam>
