What is a CYS file? A CYS file is a session file created by Cytoscape, an open-source application used for visualizing and analyzing complex networks. It stores a complete Cytoscape session, including the loaded network data, visual layouts, applied styles, and any related metadata or annotations. CYS files enable users to save their entire Cytoscape workspace, allowing them to close the program and resume work later without losing progress.
More Information Cytoscape is often used in biology, social science, and other research fields to explore relationships among large sets of data. Researchers and data analysts commonly use CYS files to share Cytoscape projects with collaborators or to archive analysis sessions for future reference. The CYS files make it possible to preserve both the structure of the data and the appearance of the visualization. By reopening a CYS file in Cytoscape, users can restore the session exactly as it was, including all open networks and analysis settings.

A CYS file may also be a summary report created by Hot Neuron Clustify, a program used to organize and analyze large sets of documents. It contains information in the XML standard, such as the total number of documents analyzed, the number of clusters created, and distribution details about document similarity.
More Information
Clustify groups similar documents into clusters to help users identify duplicates, near-duplicates, and related content. When the clustering process is complete, the software generates a CYS file to record the overall results and statistics of the analysis. The CYS file provides an overview of the clustering outcome without exposing individual document details, allowing data analysts, e-discovery professionals, and other types of users to assess clustering quality, compare results between runs, or integrate summary data into reports or automated workflows.
How to open a CYS file
You can open CYS files with Hot Neuron Clustify in Windows. Since CYS files store information in the XML standard, you can also open and view CYS files with a text editor, such as Microsoft Notepad (Windows) and Apple TextEdit (macOS).
