File type specification:
The CDT file extension is related to the Stanford Microarray Database clustered data table file format.
When you cluster a .pcl file you will generate a .cdt (clustered data table) file, which will contain the original data, but reordered, to reflect the clustering. In addition, if you clustered by genes, you will get a .gtr file (gene tree), and if you clustered by experiments you will get a .atr file (array tree). These tree file reflect the history of how the cluster was built, and can be used to construct how the tree(s) should look.
