Winter Term 2003/2004

Workshop

Practical Analysis of Gene Expression Data

Jointly taught by:

  • Korbinian Strimmer, Juliane Schäfer, Anne-Laure Boulesteix (Statistics/LMU), and
  • Alexander Yassouridis, Klaus Hechenbichler, Bertram Müller-Myhsok, Markus Panhuysen, Benno Pütz, Daria Salyakina, Klaus Schliep, Shaun Seaman (Max Planck Institute for Psychiatry).

Registration:

For participation please register (until 31 January 2004) with either Korbinian Strimmer (email) or Alexander Yassouridis (email).

Overview:

This microarray workshop provides a practical introduction to statistical and computational aspects of gene expression analysis. Emphasis is put both on the theoretical background, such as normalization procedures, differential expression, ANOVA, and clustering and classification procedures, as well as on practical exercises using R packages for gene expression analysis (in particular the Bioconductor packages).

The course runs full four days (10:00-17:00) from 16 to 19 February 2004 and takes place in the computer room of the Department of Statistics.

Agenda:

  • Introduction to microarray technology
  • Normalization procedures
  • Differential expression
  • Clustering gene expression data
  • Classification of tissue samples
  • Inference of genetic networks

On each topic there will be both lectures and practical excercises.

For further details please download the course flyer (pdf) and the timetable and program (pdf).

The data sets required for the exercises on clustering and classification (day 3) are also available (compressed with gzip): carci.rda, nci.rda, leukemia.rdata, srbct.rdata, colon.rdata.

The R packages mainly used are the Bioconductor packages and the GeneTS package.
