Additional file 2:

Gene set definitions for E. coli. This is a tab-delimited file with 4290 rows (one for each gene) and 338 columns. The first column gives the gene ID (b-number); the remaining 337 indicate whether (1) or not (0) the gene is in the gene set. There are 337 gene sets for E. coli based on SEED subsystems.

Additional file 3:

Gene set names for E. coli. This is a tab-delimited file with 337 rows (one for each gene set) and 3 columns. The first column is the SEED subsystem name, the second is the numeric identifier for the set (1–337; corresponds to the order of sets in Additional file #2), and the third column indicates the number of genes in the set.

Additional file 4:

Gene set definitions for S. typhimurium. This is a tab-delimited file with 4493 rows (one for each gene) and 332 columns. The first column gives the gene ID (STM number); the remaining 331 indicate whether (1) or not (0) the gene is in the gene set. There are 331 gene sets for S. typhimurium based on SEED subsystems.
