| Data processing |
Raw fastq files have been analysed with RNAsik pipeline (Tsyganov et al. 2018) to produce raw genes count matrix and various quality control metrics.
For this analysis RNAsik pipeline (Tsyganov et al. 2018) ran with BWA mem aligner option (Li H et al. 2013 ) and reads were quantified with featureCounts (Liao, Smyth, and Shi 2014).
The reference GFF and FASTA files were downloaded from RefSeq database bl21_de3 (https://www.ncbi.nlm.nih.gov/nuccore/CP001509)
Raw counts were then analysed with Degust (Powell 2015) web tool to do differential expression analysis to produce list of differentially expressed genes and several quality plots including classical multidimensional scaling (MDS) and MA plots
In this analysis limma voom (Law et al. 2014) was used for differential expression analysis. Degust (Powell 2015) largely follows limma voom workflow with typical conts per million (CPM) library size normalisation and trimmed mean of M values (TMM) normalisation (Robinson and Oshlack 2010) for RNA composition normalisation.
