Figure 1From: Projection to latent pathways (PLP): a constrained projection to latent variables (PLS) method for elementary flux modes discriminationSchematic representation of decomposition operations performed by PLS and PLP algorithms. The main differences between PLS and PLP are related to the computation of Y-loadings. In PLS Q are abstract variables calculated to maximise correlation between X and Y, while in PLP Q comprises a subset of active EFM.Back to article page
