Statistical issues with quantitative proteomics data
Dr Jean Yee Hwa Yang (The University of Sydney)
La Trobe University
Protein quantisation using mass spectrometry is a recent, powerful platform for determining relative protein levels for thousands of proteins simultaneously. In recent years, we have witnessed rapid development in spectrometry technologies; however, the statistical analysis of raw tandem spectra as well as processed data remains a challenging task. In this talk, we will use biological studies to illustrate the statistical challenges associated with analysing data from such a platform and approaches for extracting biological patterns and information. My discussion will focus on two separate aspects. The pre-processing component will examine various preprocessing approaches and describe a new method for enhancing deterministic protein identification from identified peptide sequences. The second component will discuss issues associated with downstream analysis.
