Chemometrics in Metabolomics

Course Description

Metabolomics is an emerging discipline in the field of systems biology. It requires some specialized chemometric methods to both pre-process and process the complex data. Examples of these methods will be given and one method specifically designed to analyze metabolomics data (ASCA) will be explained in more detail. The course will also include hands-on computer time for participants to work on an ASCA problem using MATLAB and ASCA software.
