Fig. 3From: AutoRoot: open-source software employing a novel image analysis approach to support fully-automated plant phenotyping Scatter plots for pairs of proxy traits, for PEG (red) and control (black) datasets. Inset biplot of the PCA across components 1 and 2. Note how many of the proxy traits clearly separate the two experimental conditions. Therefore, they can be used to detect phenotypically different datasets directly (see Additional file 2: Figure S2 for example images)Back to article page
