Feature extraction from simulated data. a, b, c, Distribution of estimated MetICA sources (for three background noise levels) when projected on a 2D CCA space. Sources belonging to the same hierarchical cluster have the same color. d The sample distribution on PC11 and PC15 used for SX generation: samples (top of edges) corresponding to fermentation triplicates of the same strain are connected to their gravity center (rectangle). e The sample distribution of the centrotypes of the red cluster and blue cluster. For any background noise level tested, the centrotypes of these two clusters carry the same strain rankings as PC11 and PC15
