Release 2.6 Use Cases / Overall Themes

(Under construction)

• Relatively smaller set of new features.
• Cleaning up backlogs (from 2.5)

Timeline

Release Date: TBD

Release 2.6 Feature Ideas (VERY tentative)

New Features

• Support for ["Molecular Interaction Maps"] and/or SBGN. Lead: Allan [Agilent, MSKCC, NCI?] To correctly render Molecular interaction maps or Systems Biology Graphical Notation would require the development of several new node shapes and other graphical capabilities. We will want to incorporate this support incrementally over two or more versions of Cytoscape. Some possible features (in order of difficulty, only a subset to be implemented):

  • links on Nodes for Processes, i.e. double-click on a Process Node and jump to a new Network View.

  • editor, renderer, and graph layout support for 90-degree geometry, e.g. snap-to-grid.
  • Coordinate System (like a legend except that it accommodates pans/zooms/viewport changes).
  • support for adding graphical annotations on an annotation plane (see layered graphics below).
  • editor, renderer, and graph layout support for new edge types, new node shapes.
  • add, drag/drop structured evidence onto a Node or Edge
  • editor 'templates' for composites
  • sub-molecular entities, e.g. binding sites, domains, splice variants. Introduce the construct of a 'site' on a node.

• Support for layered graphics. Lead: Ben [MSKCC, Agilent, Gladstone?] The goal is to allow users to add images or other graphical objects to the background and foreground of networks to further enhance network visualizations.

• Cytoscape Themes. Leads: Sarah and Alex. We think it would be useful to provide customized versions of Cytoscape for specific users. An example would be a biologist themed release that would include all plugins to support import/export of biological file formats.

• Dynamic Filters. Lead: Peng. The intent for the changes to the filters UI is to allow dynamic selection of nodes and edges based sliders and other widgets in the filter. This isn't possible for 2.5 so we've pushed it to 2.6.

• ["Consolidated graph analysis plugin"] - Lead: Kei. Several graph analysis algorithms (e.g. shortest-path and graph statistics) are available as plugins, but they are not collected in a common location. We can borrow some code from [http://jung.sourceforge.net/ JUNG] project for this part. See ["Future Cytoscape Features/Simple graph statistics"] page.

• Spreadsheet capability for attribute browser. The ability to manipulate attributes within Cytoscape would provide users flexibility that Cytoscape currently doesn't have.

• ["Scripting"] Lead: Kei and Scooter? - Both general scripting language support and Cytoscape original simple scripting language.

• Attribute namespaces. Lead: Mike. Extend attributes to include the concept of a "namespace". This could be used to bind node attributes to specific networks, to specific groups, or to simply provide some assurance of uniqueness for plugin authors by binding an attribute to a plugin.

• Properties We need global properties that are saved in the .cytoscape directory automatically, in addition to the cytoscape.props. Some use cases are: saving the last directory used, saving bookmarks stored by users.

Refactoring

• Refactor the Network Manager to support selection and operations on multiple networks. It is often the case that users have hundreds of networks loaded at any given time. It would be useful to be able to perform operations (such as applying a layout) on more than one network at once. Also, we need to separate Network Panel's tree data model from GUI.

• Undirected Edges Lead: Mike. Add proper support for undirected edges.

• In memory session saving Explore writing a session file without first writing tmp files. We should be able to do everything in memory. This will prevent many permission error bugs.

• Better headless mode (communicating to scripting feature?)

Backlogs from 2.5

• Linkout from Attribute Browser
• Cytoscape Class Cleanup

• CyAttributes Name Clashes

• Clean up old bugs

Move to 3.0

• Refactor event handling, GINY, and others. As always, there is much refactoring to be done. Cleaning up event handling is particularly important because the current disorder is causing problems for plugin writers.
