SRR057750	GSE21341	GSM533307	GPL10328	PMID_20671182	time point 6	genome-wide measurement of mRNA lifetime in Escherichia coli	GPL10328: Illumina Genome Analyzer II (Escherichia coli)	data_processing	Sequence reads were obtained and mapped to the W3110 genome (NCBI) using the Illumina Genome Analyzer Pipeline. All reads mapping with two or fewer mismatches were retained. Repeated sequences were ignored (rRNA). The counts in each sample was normalized by ssrA RNA and then converted to logarithmic values. A value of 1 was added to every count before the logarithmic conversion to avoid an undefined logarithm of 0. The lifetime was determined from the inverse of the slope of a linear fit to the logarithmic values. PGCGROWTHCONDITIONS

A second rRNA removal step was performed following the protocol described in Affymetrix Expression Handbook, substituting enzymes MMLV (Ambion), RNase H (NEB), and DnaseI (Amplification grade, Invitrogen).

RNA seq libraries were prepared according to Illumna’s protocol, using NEB enzymes and barcoded adapters (Integrated DNA Technologies). The libraries were pooled and sequenced with an Illumina GA II machine (Center for Systems Biology, Harvard University). PGCGROWTHCONDITIONS
