This figure illustrates the operations performed at each merging step in Fig. 5. The colors represent the metabolites, while the factory and gear represent the imputation model stages created from the relevant datasets. The green piece represents the common metabolites in the two datasets. The orange and purple pieces need to be filled with the corresponding models. The model associated with the dataset of green and purple pieces fills the purple area in the other dataset with green and orange pieces. On the other hand, the orange area in is similarly filled with the model trained on . Then, the two datasets are merged. The similarity in color but jagged edges of the model outputs emphasizes the dependency on the model
