Partek Genomics Suite offers two alternatives to Hierarchical clustering - K-Means clustering and Self-Organizing Map. For a more in-depth description of how Partek Genomics Suite performs these different forms of clustering analysis, please see Chapter 8 Hierarchical & Partitioning Clustering of the Partek Manual. The Partek Manual can be accessed through Partek^® Genomics Suite under ^® under Help > On-Line Help. 

Visualizing Hierarchical Clustering

To illustrate the capabilities and customization options of hierarchical clustering in Partek Genomics Suite, we will explore an example of hierarchical clustering drawn from the tutorial Gene Expression Analysis. The data set in this tutorial includes gene expression data from patients with or without Down syndrome. Using this data set, 23 highly differentially expressed genes between Down syndrome and normal patient tissues were identified. These 23 differentially regulated genes were then used to perform hierarchical clustering of the samples. Follow the steps outlined in Hierarchical Clustering and Adding Information to Gene Lists to Performing hierarchical clustering to perform hierarchical clustering and launch the Hierarchical Clustering tab (Figure 1).
