Figure 2.

A visual representation of the agreement matrix used as input to robust and consensus clustering. The n × n matrix is upper triangular. Each cell within the matrix, referenced by column i and row j, represents the number of clustering methods that have placed gene i and gene j into the same cluster. In other words, the number represents the agreement between clustering methods concerning gene i and gene j.
