With chemometrics in mind (QSAR, data mining, …), I have started working on matrix support in Bioclipse, because the matrix is the important step between (bio-)molecular content and statistical analysis. I implemented this such that the actual matrix implementation can be freely chosen, that is, bc_statistical provides a IMatrixImplementation extension point.

The Self-organizing map (SOM) is a popular (again) and intuitive non-linear mapping method: it transforms a multidimensional space into two dimensions (normally: they are so easy to visualize). Latino and Aires-de-Sousa published a paper that uses this method to analyze the whole KEGG pathway database: Genome-Scale Classification of Metabolic Reactions: A Chemoinformatics Approach (DOI: anie.200503833). The method is based on earlier

If you have read my previous post and visited that other blog, you might have noted the Technorati keywords . Or tags, really, as explained in this rel=“tag” microformat.
