| Extracted molecule |
total RNA |
| Extraction protocol |
rRNA was depleted from purified total RNA using the Ribo-Zero Gram-Negative Bacteria kit (Illumina). rRNA-depleted samples were then cleaned up with the RNA Clean & Concentrator-5 (Zymo Research) and eluted in 15ul. library strategy RNA-Seq. RNA-Seq libraries were prepared using the NEBNext® Ultra™ Directional RNA Library Prep Kit for Illumina® (E7420; New England BioLabs).

General read quality was evaluated using FastQC v0.11.2
Genome and GTF files were downloaded from NCBI and indexed using bowtie2-build (Bowtie2 v2.3.1).
FASTQs were filtered and trimmed using fastq-mcf (ea-utils v1.1.2) using paramteres "-q 20 -x 0.5" and adapter sequences from the NEBNext manual.
Filtered and trimmed reads were mapped using tophat2 (v2.1.1) using parameters "--library-type fr-firststrand --max-intron-length 5 --min-intron-length 4 --transcriptome-max-hits 1 --max-multihits 1 --no-coverage-search --no-novel-juncs --no-sort-bam
samtools v0.1.19 was used to merge and sort the accepted_hits.bam and unmapped.bam files output by tophat using commands "samtools merge -n" and "samtools sort -n"
htseq-count (htseq v0.6.1) was used to count reads per gene with the parameters "--order=name --format=bam --stranded=reverse --type=gene --idattr=locus_tag" $TH_DIR/${SAMPLE}/merged.name.bam
A Jupyter notebook containing the analysis pipeline is available at <https://gitlab.oit.duke.edu/Biostatistics_and_Bioinformatics/HTS_SummerCourse_2017/-/blob/master/Materials/Computation/Wk4_Day4_AM/analysis_nb/2017_generate_pilot_counts.ipynb>
Genome_build: GCF_000007805.1_ASM780v1
Supplementary_files_format_and_content: tab-delimited text files containing raw read counts per gene
