Format

A list with two components:

Y

Chromatin immunoprecipitation. A matrix of 180 rows and 661 columns.

classIndex

Group index of 180 patients where 1,2,3 corresponds to OxPhos, BCR and HR groups respectively.

Details

Matrix Y : Gene expression dataset from the patients with diffuse large-B-cell lymphoma (DLBCL) after chemotherapy. The data has been used for unsupervised analysis i.e. Biclustering. The data consists of expression levels of q = 661 genes from n =180 patients. Among the patients, 42, 51 and 87 of them were classified to OxPhos, BCR and HR groups, respectively. The data thus form an n by q matrix Y whose rows represent the subjects and columns correspond to the genes, and used in Rosenwald (2002).

classIndex: Out of OxPhos (oxidative phosphorylation), BCR(Bcell response) and HR (host response), the index corresponds to the groups in which these 180 subjects belongs as classified by Hoshida (2007).
