Clusters samples based on copy number aberrations.
Clustering of copy number data can be performed using either soft or hard calls. Hard calls divide the data into either losses, normals, or gains, whereas soft calls refer to the respective probabilities of these calls. The preferred choice is to use soft calls whenever they are available.
