Hierarchical Clustering: Dendrogram

The result of the expression level analysis is usually presented as a dendrogram with an accompanying expression level table that has been reordered according to the clusters:

Dendrogram showing [BD], [ABD], and [ABCD] clusters above the data table: Log₁₀ in five samples of genes B, D, A, and C
Dendrogram A, B, C, D cluster
Dendrogram A, B, D cluster
