Fig. 2From: A fuzzy method for RNA-Seq differential expression analysis in presence of multireadsGraphical interpretation of the fuzzy sets and their comparison for differential expression evaluation. The joint possibility distribution of the same gene in two samples is represented by a Cartesian product (a). The projections on a 2-dimensional plots can be exploited to evaluate the results (b). The green gene (i) has same-expression possibility = 1; the yellow gene (ii) has under-expression possibility = 1, same-expression possibility < 1; the red gene (iii) has over-expression possibility = 1, same-expression possibility = 0Back to article page
