Easy Differential Expression,c filtering step to remove probes for genes that appear to be always unexpressed or at least not differentially expressed. Second, a probe-by-probe statistical test, and third, multiple testing correction to get an attenuated test statistic through the false discovery rate (FDR). There are many vari

Annotation and Metadata,mapping them to their target genes, one will want to use the annotation of the genes and gene products to better interpret the experimental results. Often, it is beneficial to use gene annotation in the course of the primary analysis, in order to narrow down the set of data to be considered and amel

Using Graphs for Interactome Data, In this chapter, we explore a curated dataset of protein interactions and perform a statistical analysis of the relationship between protein interaction and coexpression. We also show how to access large-scale protein–protein interaction datasets from the IntAct repository at the EBI.

Hypergeometric Testing Used for Gene Set Enrichment Analysis, functional relationships among those genes that might help better elucidate the underlying biology. These methods typically rely on existing or predefined sets of genes. In this chapter we show how to carry out Hypergeometric tests to identify potentially interesting gene sets.
