The microarray data for each condition was obtained from the GEO or ArrayExpress databases, using the specified accession numbers. The differential gene expression levels obtained from analysis of this microarray data was used to make a metabolic model for each condition. These context-specific metabolic models were used to predict change in biomass production for each condition compared with the control of each microarray dataset
