- Overview
+ Introduction
- Summary

The most robust consensus NMF clustering of 499 samples using the 107 copy number focal regions was identified for k = 3 clusters. We computed the clustering for k = 2 to k = 8 and used the cophenetic correlation coefficient to determine the best solution.

- Results
+ Copy number focal events of molecular subtypes
+ Consensus and correlation matrix
+ Silhouette widths
+ Samples assignment with silhouette width
+ Marker focal events of each subtype
+ Methods & Data
