Open the Cluster program. If you don't have it, download it from http://rana.lbl.gov/EisenSoftware.htm. You may pre-filter the data if you wish; otherwise, proceed to clustering by clicking on the "Hierarchical Clustering" tab. You should see the following screen below:

The default parameters for clustering are shown in that screenshot. If you wish, you may modify these parameters or other parameters available in the Cluster program.

The resulting CDT, GTR, and ATR files will appear in your working directory and are ready for viewing under TreeView.
