SKYPE generates following results.
- Circos plot, which shows copy number of chromosomes
- Virtual SKY diagram, which shows most reasonable combinations of mutated chromosome
SKYPE implements following steps to achieve above results.
- Classify contigs as their mutational role and prune unnecessary parts
- Compress contigs by their most significant terminal node (NClose)
- Build breakend graph by connecting NClose nodes and telomere nodes
- Find all simple telomere-to-telomere paths of breakend graph
- Recover full path with normal contigs
- Optimize copy number of each paths by using customized SI-NNLS algorithm
- Visualize results
It is recommended to use ACCtools pipeline, rather than using SKYPE alone.
Results are saved as 2 png files.
- <SKYPE result folder>/<CELL_LINE_RESULT_FOLDER>/total_cov.png : Circos plot
- <SKYPE result folder>/<CELL_LINE_RESULT_FOLDER>/virtual_sky.png : Virtual SKY diagram
First argument defines cell line to analyze. Second argument(optional) defines the folder to save SKYPE result. Change THREAD variable
