What is Pathomx?
Pathomx is a workflow-based metabolomics analysis tool. It has been developed as part of my PhD to enable rapid visualisation and interpretation of metabolic data within a pathway context.
The latest release (v2.5) provides a number of novel features:
Workflow based data exploration: Workflows can be created, edited and shared using the built-in analysis workflow editor. Set up standardised analysis approaches and apply them to new data consistently. Add-remove tools to test different approaches, and re-apply tried and tested methods to new data.
Metabolic pathway exploration: Browse through the metabolic pathway database, with automated clean rendering of pathways. Add and remove metabolic pathways, show intra-pathway linkages, and map metabolic routes through the system. Browse the in-built database, following links to online resources for further information.
Metabolic data visualisation: Load experimental data gathered by mass-spectroscopy (MS) or nuclear magnetic resonance (NMR) spectroscopy and visualise metabolic changes overlaid on a a map of the sytem. Visualise gene-expression or protein quantity data alongside to explore relationships between enzyme regulation and metabolic processes. Use the built-in "Pathway Mining" tools to select the most up, down, or overall regulated pathways in the given system to identify the key mechanisms at work.
Pathomx is built on the MetaCyc pathway database itself part of the BioCyc family. The supplied database is generated via the MetaCyc API and stored locally. Licenses for the entire MetaCyc database are also available free of charge for academic and government use.
It strives to be user-friendly, intuitive and quick - and not too shabby looking.
Note: Pathomx requires installation of Graphviz for the automated pathway drawing.
pathomx is released open-source under the the GPLv3 license and is therefore free to use for whatever purposes you wish. You can clone the repository or download a built Windows 7 & 8 .msi Installer or Mac app.
Note: pathomx requires installation of Graphviz for some pathway-drawing elements.
Contributions and comments from users and developers at other institutions are most welcome. Fork the repo on github. If you have issues, bugs or feature requires please report them and I'll do what I can.
