Transcriptome data for Escherichia coli K-12

GEO data

• GPL: 199]
• arrays: A total set of 631 arrays have been compiled.
• List of selected GSE series: 1121, 4511, 4556, 4562, 4778, 6425, 6426, 6836, 6923, 7326, 7379, 7885, 8708, 9582, 9755, 9814, 10158, 10974, 11183, 12797, 13418, 17505, 17506, 17507

Raw data have been used i.e., CEL files.

Normalization

• within array normalization: RMA normalization was applied using the R/Bioconductor affy library.
• between array normalization: each value was divided by the mean of the array values i.e., x/mean(x)
