Spectral Tree Viewer

Multistage Mass Spectrometry is a method to analyze the degradation compounds into smaller molecules, improving the identification process. The process of selecting sub-spectra through the different stages results in data that is often visualized in a tree like manner. The Spectral Tree Viewer is a visualization which runs in a web browser that gives the ability to browse through the multiple spectra and visualize the chemical compounds and neutral losses.

A live demo version of the spectral tree viewer can be found at  http://viewer.metitree.nl/demo/

This project was done in collaboration with Netherlands Metabolomics Centre, Leiden/Amsterdam? Center for Drug Research and NBIC/NMC data support platform.

Technologies

We used some libraries who are available under MIT licensing. These libraries are available through our SVN repository

Drawing the trees is done with the JavaScript? library Rapheal  http://raphaeljs.com/. We used Rapheal 1.5.2 with some small fixes for Google Chrome

The chemical structures are drawn with the python OASA library  http://bkchem.zirael.org/oasa_en.html

Source access

If available, anonymous readonly subversion access works as follows:

  svn co https://trac.nbic.nl/svn/brsp201017 spectraltrees

Write access is only available to registered developers.

You can become a developer by  registering yourself if you haven't already done so, and requesting write access on the  https://trac.nbic.nl/mailman/listinfo/brsp201017-usersbrsp201017-users mailing list.
