Fold enrichment for re-ordered yeast segregant gene expression data. Enrichment of genes sharing the same biological process annotation within different size neighborhoods for re-orderings by OREO, hierarchical clustering (HC), hierarchical clustering after optimal leaf ordering (HC (Optimal)), and nsNMF after sorting on the first, second, third and fourth basis conditions (nsNMF (Factor 1), nsNMF (Factor 2), nsNMF (Factor 3), nsNMF (Factor 4), respectively). For the definition of enrichment values, see Eq. 1 in text.
