Figure 4From: Projection to latent pathways (PLP): a constrained projection to latent variables (PLS) method for elementary flux modes discriminationNormalized PLS output loadings versus reaction weighting factors of selected EFM. Blue circles and red triangles represent the loadings of the first and second PLS latent variable plotted against the corresponding metabolic reaction weighting factor of the first and second selected EFM (EFM179 and EFM1 respectively; see Tables 2 and 3).Back to article page
