This figure shows a group of unclassified ORFS that were consistently classified together by biclusters signif- icantly enriched for the Mitochondrial (42.16) & Ribosomal Proteins (12.01.01) in two independent datasets. The 6 unclassified ORFs in this predicted functional module correlate tightly over a subset of 30 sample features in (a) Gasch and (b) Hughes expression datasets. function and functional modules, that this re-assessment may provide. Competing interests The authors declare that they have no competing interests. Authors' contributions KB and PC developed the concepts which motivated the BALBOA algorithm. KB developed the algorithms and evaluation and drafted the manuscript. PC advised on the methodology used in the evaluation section of the paper. All authors read and approved the final manuscript.
