Welcome to PathCase

PathCase is a web-based bioinformatics tool to store, query, and visualize metabolic pathways. For more information on PathCase, please check out the links located on the left. PathCase currently runs on three different data sets: (i) KEGG pathways, (ii) Biocyc Human pathways (alpha version), and (iii) sample pathways from literature. Please click on one of the versions below to start using PathCase.




What is New:


>> February 2008
  • A new version of PathCase running on Biocyc Human pathways has been released (still in alpha version).
  • For several KEGG pathways, frozen layouts have been tailored and made publicly available.
  • The visualization applet now allows users with administrative privileges to modify and save layouts for pathways.
  • Cofactors are now drawn as curved edges which makes it easier to distinguish cofactors from other reactants.
  • Visualization of activators, inhibitors, and regulators are improved via careful positioning with respect to their reactions.
  • PathCase has a new logo.

>> November 2007
  • The Advanced Query Interface now supports path and neighborhood queries and now has more descriptive text.
  • Graph layouts are now improved and various minor improvements to the interactive visualizations.
  • A tool, called BiopaxViz, has been integrated to allow users to visualize pathways in Biopax format.

>> September 2007
  • In the Advanced Query Interface, only values that can return results are presented as input suggestions.
  • Built-in queries now allow for the user to specify a set of pathways on which they are executed.
  • KEGG data has been updated with the most recent public release as of September 2007.
  • Now supports Google Search within PathCase and a link to bookmark the current page.

>> June 2007
  • A built-in query is developed to search for pathways that are significantly enriched by a user-provided set of genes.
  • PathCase now allows users to visualize any arbitrary select set of pathways through a built-in query.

>> May 2007
  • Advanced Query Interface (AQI) is released. AQI allows users to dynamically construct query interfaces that best fit to what they have in mind as a query.
  • KEGG data has been updated with the most recent public release as of May 2007.

>> April 2007
  • A new PathCase version running on KEGG pathways data is released.
  • Visualization now has a magnifier tool to instantly zoom into different parts of graphs
  • Enzyme-only and Metabolite-only visualizations of pathways are integrated to PathCase.

>> March 2007
  • New graph layout algorithms are made available to the users with various user-adjustable parameters.
  • A graph object explorer is developed to allow users to eliminate selected nodes.

>> January 2007
  • A new graph layout generation library (yFiles) has replaced previously used Tom Sawyer software which allows faster and scalable graph visualizations.
  • Data model of the underlying PathCase database is made publicly available.
