Representation of the three sources extracted in unsupervised mode for GL+ME.

Representation of the three sources to the two tumor types (GL and ME) involved. They include the percentage of cases mainly represented by each source (by tumor type), and the number of cases from the total, in parentheses. Sources were extracted in an unsupervised mode using Convex-NMF for the aggressive tumors group (GL + ME), using the training data at both STE and LTE.
