Episomizer is currently a semi-automatic computational pipeline to construct circular DNA structures through identifying SVs connecting the boundaries of highly amplified CNA segments followed by a graph theoretical algorithm that searches for cyclic graphs.

The source code, demo dataset, and documentation can be found at GitHub: https://github.com/stjude/Episomizer. We are still in the process of fully automating the pipeline and adding other features including precise copy number estimation of the identified circular structures.
