Cytoscape Data Services PlugIn ------------------------------ I. Introduction ================ This directory contains a copy of the Cytoscape Data Services PlugIn. This PlugIn enables Cytoscape to import/export to multiple file formats. The current release includes support for: 1. Proteomics Standards Initiative Molecular Interaction (PSI-MI) XML Format. PSI-MI is a new XML format used to represent and exchange protein-protein interaction data. Information is available online at: http://psidev.sourceforge.net/. You can load PSI-MI files from your local file system or from any arbitrary URL. You can also export Cytoscape graphs to PSI-MI format. 2. GEO Simple Omnibus Format in Text (SOFT). SOFT is a text file format used to represent and exchange Gene Expression Data. Information is available online at: http://www.ncbi.nlm.nih.gov/geo/info/soft.html. You can load SOFT files from your local file system or from any arbitrary URL. Export functionality is not currently supported. II. Installation Instructions ============================== To use the Data Services PlugIn, you must first obtain a copy of Cytoscape, Version 1.1. You can download a copy from: http://www.cytsoscape.org. Once you have downloaded Cytoscape and verified that it works, proceed with the next steps. 1. Copy the ds_plugin.jar file to your [Cytoscape_Home]/plugins directory. 2. Restart Cytoscape. For example, on Unix/Linux or MacOS X, run: cytoscape.sh On Windows, run: cytoscape.bat III. Using the PSI-MI PlugIn ============================= Once Cytoscape starts, select "PlugIns" from the Main Menu. You will see three options here: Import PSI-MI Data from File, Import PSI-MI Data from Web, and Export Data to PSI-MI Format. 1. Select PlugIns --> Load PSI Data from File. 2. Select one of the sample PSI-MI Files in the sampleData/ directory. Cytoscape will now load the PSI-MI file, and show a graphical representation of the file. If you want to view information about a specific node or edge, right click on it, and you will see the node/edge browser. To export data in PSI-MI format, select Plugins --> Export Data to PSI-MI Format. IV. Using the SOFT PlugIn ========================== The SOFT PlugIn reads in expression data, and adds this data to an existing Cytoscape graph. 1. First, load up a sample Interaction file. Select File --> Load --> Interaction. Then, specify a sample SIF file, such as sampleData/GDS362.sif. 2. Select PlugIns --> Import GEO SOFT Data from File. Then, specify a sample SOFT file, such as sampleData/GDS362.soft. 3. Select any node, and right click on it. Gene Expression data will now appear within the Cytoscape Node Browser. V. Bugs / Feature Requests ============================ If you encounter a bug with this PlugIn, or have a feature suggestion, we encourage you to use the Cytoscape Bug Tracker: http://www.cbio.mskcc.org/cytoscape/bugs/. If you log a bug, we will automatically email you when the bug is resolved. VI.
