Usually, RNA-Seq data analysis needs skills in programming and bioinformatics. We aimed at developing easy-to-use pipeline covering multiple aspects of DE analysis. Here we present RTrans pipeline aimed at evaluating differential gene expression, pathway enrichment, WGCNA co-expression analysis and visualization. It provides rapid analysis of read counts data including MANOVA, paired tests, non-parametric tests. RTrans represents a versatile pipeline facilitating DE analysis based on RNA-Seq and other quantitative data.

Coli only. However, there is a problem due to the low accuracy of Рћ-antigen cluster identification in the genome. Pipeline, which was created due the work, solves this problem and can be used to find and annotate a cluster of genes in genome of the most gram-negative bacteria.
