Särskild behörighet (1) Basic knowledge in descriptive statistics. (2) Basic knowledge in R-programming language.
Kursens lärandemål At the end of the course the students should be able to
- Understand the overall theoretical principles behind the individual steps in the analysis of mRNA, DNA-methylation and DNA arrays, including the preconditions and assumptions in the individual steps of the analysis.
- Show an ability to perform independent microarray analysis.
- Design microarray-based experiments for an optimum statistical analysis.
- Perform integrative data analysis of DNA-methylation and mRNA based experiments.
- Analyze the obtained data functionally.
Kursens innehåll The students will be provided with tools to explore and analyze microarray data sets. With "example-oriented" exercises the most important cases and methods under R environment will be reviewed. One will learn new concepts in R including the necessary background to increase ones experience in R by using available documentation and public tools. Specifically the Bioconductor, an open software source for bioinformatics will be used. Thirdly, students will be provided with tools to integrate their data with public available resources in addition to combine several data types. Sessions: 1. Introduction to R & array analysis: Bioconductor. 2. Overview of the microarray technology -Theory and Practice. 3. Introduction to array processing: a. Quality control. b. Normalization. c. Batch effect. 4. Analyze mRNA-arrays: Affymetrix, Illumina. a. Differential Expression Analysis: the identification of genes varying among different conditions. b. Fold change analysis. 5. Pipelines to analyze DNA-methylation arrays: Nimblegen, Illumina 450K. a. Estimation of DNA-methylation by arrays. b. Normalization in DNA-methylation arrays. c. Differential methylation. 6. Pipelines to analyze genotype arrays: computing odd ratios. 7. Advance tools to analyze microarray data: a. Distance measures and clustering. b. Class Discovery (i.e. PCA). 8. Functional analysis of the results: a. Gene Set Enrichment Analysis: the identification of pathways. b. Network Analysis. 9. How to become independent in R-Bioconductor. 10. Notes on how to integrate different data types?
Arbetsformer Lectures: 30% Computer Labs: 50% Project work: 20%
Obligatoriska moment Attendance is compulsory. In case of absence, lectures can be compensated with extra reading and computing assignments according to instructions from the course leaders.
Examination The examination will take into account two elements: - Resolution of the exercises during the computer labs. (with support from the lecturers.) - Project: individually, a data set must be analyzed by the different methods (and supporting the results with plots) shown in the course. The data set can come from the students, or if not a data set will be provided.
