.path files for editing pathways using Pathway Editor

The Pathway Editor is a program for managing, visualizing, and editing signaling and metabolic pathways. Pathways may be created from scratch or accessed by opening a .path file. Time course graphs for both lipids and genes, and data for technical and biological replicates for lipids can be displayed within the Pathway Editor. For lipids, the Pathway Editor also provides links to KEGG and to LMSD records, with lipid structures and annotations. Links to annotations in GeneEntrez and the Mouse Genome Database are provided for genes.

Please see our Pathway Editor tutorial for an overview of Pathway Editor features, including how to start the Pathway Editor, access LIPID MAPS pathways and display LIPID MAPS and user-provided experimental data, create pathways from scratch, and edit and save pathway files and images. Instructions for working with SBML and BioPAX formats are also provided.

On Safari and Chrome browsers, the Pathway Editor does not automatically start up when the Pathway Editor is downloaded. In these cases, the Pathway Editor may be started by double-clicking the .jnlp file icon in a Finder window or typing the following in a terminal window:

The Web Start version has been tested on the following versions of LINUX:

  • LINUX Ubuntu release 12.04 64-bit virtual machine containing 3.9 GB memory and 4 Intel Xeon 2GHz CPU with a Java 6 version of Open JDK, and
  • LINUX CentOS (Red Hat) release 6.5 virtual machine with 65 GB memory and 22 Intel Xeon 2 GHz CPU, with Oracle Java 7.

An installed version of the Pathway Editor for LINUX is not available at this time.

On CentOS installations, the OpenJDK Java which is installed by default may not contain Java Web Start. Java 7, which contains Web Start, may be installed by following the directions on

The version of Java that is used to run the Web Start version may be set in the browser. However, given difficulties associated with finding Java settings in browser menus, the Web Start version may be downloaded and started from a terminal window by entering the text

UNIX and other platforms
The Pathway Editor has not been tested on UNIX and other platforms.

Software requirements:

The Pathway Editor uses Java Web Start 1.6 or later version and JOGL(Java Open Graphics Language) (JOGL is downloaded as part of the Pathway Editor). If you use the Web Start version, please install a Java Runtime Environment.
