 \- **Mathematical transformation** can be applied to clustered data before clustering and visualization. Data used for the filtering step are not modified by this transformation.

+\- **Distance measure** used to cluster rows and columns. For "euclidean", "manhattan" and "binary" distances the 'dist' R function is directly called, for "pearson", "spearman" and "kendall" distances the '(1-correlation)/2' term is used  as a classical distance, for "absPearson", "absSpearman" and "absKendall" the 'abs(1-correlation)'' term is used.
