- Overview
+ Introduction
- Summary

The most robust consensus NMF clustering of 123 samples using the 195 most variable proteins was identified for k = 5 clusters. We computed the clustering for k = 2 to k = 10 and uused the cophenetic correlation coefficient and the average silhouette width calculation to determine the robust clusters.

- Results
+ Protein expression patterns of molecular subtypes
+ Silhouette widths, Cophenetic Correlation Coefficients and Consensus matrix
+ Samples assignment with silhouette width
+ Marker proteins of each subtype
+ Methods & Data
