Read coverage maps and RPKM data was subsequently generated by Geneious.īAM files of the resulting assembly data were exported to JMP Genomics (SAS). The assembly process was set to medium/low sensitivity on Geneious, with the following parameters: 10% gaps allowed per read word length of 18 index word length of 13 words repeated more than 12 times ignored 20% maximum mismatches per read and maximum ambiguity of 4 Removal of the host genome/transcriptome reads is performed to decrease background noise (eg, host and environmental reads) and increase the frequency of pathogen reads 8.

Sequencing reads (approximately 13 to 25 million per sample) were imported into Geneious Pro (Biomatters) and assembled to the reference chromosome MG1655 (GenBank Accession Number 000913.2). The raw data from a sequencing platform is usually cleaned, trimmed, and filtered to remove low-quality and duplicate reads. Users are encouraged to normalize raw read count values if a subset of genes is investigated. Normalized values should be used only within the context of the entire gene set. RNA libraries were prepared for sequencing using standard Illumina protocols RNA-Seq expression level read counts produced by HT-Seq are normalized using two similar methods: FPKM and FPKM-UQ. RNA samples were then treated with DNase (New England Biolabs) for 30 min at 37 ☌. MG1655 pCA24N and MG1655 pCA24N-Mfd cells were grown to an OD560 of approximately 0.25 and treated with 100 μM IPTG for 1 hour.Ĭells were grown to approximately mid-log phase (OD560 = approximately 0.5) in LB.Ĭell pellets were lysed and RNA collected using Qiagen’s RNeasy Plus Mini Kit with Qiagen Bacteria Protect RNA kit.

We offer the following resources to help. At Illumina, our goal is to apply innovative technologies to the analysis of genetic variation and function, making studies possible that were not even imaginable just a few years ago. The version number of this tutorial is 1.0, and for now it is tailored for Illumina paired-end shotgun sequencing with large inserts (i.e., no substantial overlap between two reads in a given pair).
