Experimental design

Central to expression analysis in the CLC Genomics Workbenchis the concept of the sample. For microarray data, a sample would typically consist of the expression values from one array. Within a sample, there are a number of features, usually genes, and their associated expression levels.

Importing expression data into the Workbench as samples is described in Microarray data formats.

The first step towards analyzing this expression data is to create an Experiment, which contains information about which samples belong to which groups.
