Convert CYS to another file type

To convert CYS sessions to another format, you need Cytoscape or other Data software.

Convert a file to CYS

To convert other file formats to the "Network Session Archive" file type, you need software like Cytoscape or a similar tool.


About CYS files

.cys files primarily function as biological network session archives for Cytoscape, a popular open-source software platform designed for visualizing complex networks and integrating them with attribute data. Under the hood, these files use standard ZIP compression to bundle network graphs, node attributes, edge data, visual styles, and user interface states into a single directory structure. Less frequently, the .cys extension is used as an architectural CAD symbol file for the discontinued Data Becker Cyber-House software, or as a summary file for Clustify by Hot Neuron. The main disadvantage of the .cys format is its rigid dependency on the host software. It is a proprietary, closed session container that forces collaborators to install a heavy desktop application just to view a simple network map. Standard web browsers cannot open these files, and typical document viewers fail to parse the embedded XML network schemas. This creates serious friction when trying to quickly share research or visual graphs with non-technical stakeholders. To share network visualizations effectively, users must export the .cys data from within Cytoscape to standard formats like PDF, PNG, or vector SVG. However, if you only have the session file and no software, standard online converters fail to process it because it is not a flat image or document, but a complex data directory. This file format is notoriously difficult to open or convert directly, as usually only the original software can properly read or export the structured network relationships. Fortunately, just drag and drop your file onto convert.guru to identify the format, inspect the file structure, and see its internal text. Because our analysis detects the supported underlying ZIP embedded format, viewing the raw XML tables or extracting the session data may still be entirely possible.

Convert.Guru analyzes your CYS file, detects the exact format, and lets you read the text inside.

Users also converted CX, FPK and WAD files.

The CYS Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CYS converter.
