Microarray Data Analysis n n n Each probe location associated with gene Measure the amount of m. RNA Color indicates degree of gene expression Compare different samples (normal/disease) Track same sample over time Questions – Which genes are related to this disease? – Which genes behave in a similar manner? – What is the function of a gene? n Clustering – Hierarchical – K-means CSE 5331/7331 F'07 11
