Data Analysis: General Workflow & Analysis Options Duke Microarray Core Facility Zhengzheng Wei July. 2011
Overall Workflow • Normalization (RMA, MAS5) • Outlier Sample Removal (Affymetrix QC matrics, PCA, intensity histogram) • Gene Selection (ANOVA, multiway ANOVA, paired t-test, Fold Change…) • Gene annotations • Venn Diagram for Genelists • Clustering (unsupervised hierarchical clustering) • Gene Ontology Analysis (GATHER, Partek GO Enrichment, DAVID) • Pathway Analysis (MetaCore, DAVID, KEGG Pathways)
Other Analysis Options • microRNA microarray data analysis • Exon array data analysis • Integrate microRNA data with mRNA expression data • Class prediction (K-Nearest Neighbor, support vector machine etc.) • Survival analysis • Power analysis • Chromosome view of expression data • Data filtering based on expression • Data transformations (impute missing data, scaling, quantile normalization, normalize to control, log transformation, normalize to baseline, loess, batch effect removal etc.)
