Having problems to resolve the following error in the tutorial code:

rib = Ribosome(id='rib',

Related to this. A number of your scripts refer to .json files in the /model directory that don't exist (e.g. ecoli = load_json_model('models/RelaxedModel iJO1366_T1E1N1_350_enz_256_bins__20180830_121200.json') in iJO1366_plot_growth_regions.py). Is that intended?
