RSS HLG meeting: Analysing metabolomics' data: A challenging task
SPEAKER: Marianne Defernez - Institute of Food Research
ABSTRACT
Metabolomics is truly multi-disciplinary: It requires a multitude of skills for the research to be successful, ranging from spectroscopic and statistical expertise to in-depth knowledge of the biological systems under study. In this talk I will focus on the data analysis and show why and how some of the statistical methods used have evolved since the term 'metabolomics' was first coined twelve years ago. This will provide an opportunity to highlight current trends and limitations. It will also demonstrate that the data analysis should not be seen simply as the concluding part of an investigation; it is in fact greatly influenced by upstream steps. In particular the data pre-treatment necessarily to make the raw data suitable for the statistical analysis itself has a huge impact on the outcome, and I will discuss this issue for both NMR, and LC and GC-MS data. The talk will show the benefit of having a better appreciation of the overall procedure required for investigations in this field.
This meeting room is on the third floor and at the Eastern end of the Polwarth Building above main entrance door. A lift is available. No swipe cards will be needed to access this building in the afternoon. A map is available, http://www.abdn.ac.uk/maps/foresterhill.php , and the "hybrid" option does show the shape and colour of the buildings for those unfamiliar with the site.
