Erratum: Author Correction: Environmentally Optimal, Nutritionally Sound, Protein and Energy Conserving Plant Based Alternatives to U.S. Meat (Scientific Reports, (2019), 9, 1, (10345), 10.1038/s41598-019-46590-1)

This Article contained errors. Immediately prior to publication the Authors discovered an error in the code used in the study in the naming of a plant food item. The authors replaced USDA plant item names, which are very long and contain too much information for graphical presentation, with shorter names. The authors used a Matlab cell array, in which items are indexed with values incremented by one for each added item. In the original code, one index in this item list was erroneously repeated, which meant that reported plant names were for items with an index off by one (for example, green peppers were listed instead of green peas which preceded them in the alphabetized list, pears replaced peanuts, and so on). This affects presentations of the data in Figure 3, 4, S1, and S2 as well the names of food items presented in the text. In addressing this issue, the authors revisited all calculations. Because the results are derived using a Monte Carlo code whose randomization this time around is distinct from the original one, this resulted in minor differences in all other figures and in the numerical values reported in Table 1. These differences arose exclusively from being derived from two distinct randomizations. The item naming errors in the paper are corrected and apart from the randomization-related differences have no effect on the environmental and nutritional improvements or on the paper’s conclusions.
