 ## Example applications
 Two use cases of the workflow are demonstrated using two genome-scale models, (1) iAF1260 (*E. coli*) and (2) Recon 2.2 (human) which are respectively described in the MATLAB tutorials, tutorial_efmviz_ecoli.mlx and tutorial_efmviz_recon.mlx. Currently, the workflow using COBRA toolbox is available here. All the funtions and input files for the use cases are provided under core/inputs
