MB-VIOP results for the synthetic data set SD16_235GLU. An overview of the 4-block (D1–D4) system and its interactions is shown at the top right of the figure. The normalized loadings directly extracted from the synthetic dataset (not from the model) are provided at the top left. For the whole figure, the color code is indicated in the legend (pink is used for unique, black and blue for global, cyan (D1–D4) and orange (D1–D2) for local information related to two-block interactions, and green for local information related to the three-block interaction (D2–D3–D4)). The MB-VIOP plots are distributed by columns according to type of interpreted variation, and by rows according to data block. The important variables are the ones with MB-VIOP values above the red line (MB-VIOP > 1). A more detailed interpretation of the results of this figure is given in section "Evidence of the reliability and the efficiency of MB-VIOP using synthetic data"
