Tool for plotting gene fusion events detected by various tools using Circos.
FsnViz is a Python tool for plotting RNA-seq fusion events using Circos plots. It parses outputs of gene fusion finding tools and creates Circos plots out of it.
Currently it accepts outputs of the following gene fusion finding tool:
- FsnViz is tested on the following Python versions:
- and the following Circos versions:
Other Circos versions may be used but they are not guaranteed to work.
You can download the latest version via pip:
$ pip install fsnviz
Circos needs to be installed separately.
FsnViz needs only a result file of the gene fusion finding tool:
$ fsnviz star-fusion /path/to/result/file
With the invocation above, it will create the Circos plot as an SVG image called fsnviz.svg in the current directory. You can adjust the output behavior using some flags such as:
The --output-dir flag to set the output directory. If it does not exist, it will be created for you.
The --base-name flag to set the base name of the Circos plot (the default is fsnviz). Filename extensions are added accordingly.
The --karyotype flag to set the Circos reference karyotype. Currently only human.hg19 and human.hg38 are available.
For a complete list, check out the help via fsnviz --help.
Initial circos templates were based on the Circos templates of viewFusion, written by Jiang Li.
