RNAlysis: analyze your RNA sequencing data without writing a single line of code

Abstract

Background Among the major challenges in next-generation sequencing experiments are exploratory data analysis, interpreting trends, identifying potential targets/candidates, and visualizing the results clearly and intuitively. These hurdles are further heightened for researchers who are not experienced in writing computer code since most available analysis tools require programming skills. Even for proficient computational biologists, an efficient and replicable system is warranted to generate standardized results. Results We have developed RNAlysis, a modular Python-based analysis software for RNA sequencing data. RNAlysis allows users to build customized analysis pipelines suiting their specific research questions, going all the way from raw FASTQ files (adapter trimming, alignment, and feature counting), through exploratory data analysis and data visualization, clustering analysis, and gene set enrichment analysis. RNAlysis provides a friendly graphical user interface, allowing researchers to analyze data without writing code. We demonstrate the use of RNAlysis by analyzing RNA sequencing data from different studies using C.elegans nematodes. We note that the software applies equally to data obtained from any organism with an existing reference genome. Conclusions RNAlysis is suitable for investigating various biological questions, allowing researchers to more accurately and reproducibly run comprehensive bioinformatic analyses. It functions as a gateway into RNA sequencing analysis for less computer-savvy researchers, but can also help experienced bioinformaticians make their analyses more robust and efficient, as it offers diverse tools, scalability, automation, and standardization between analyses.

“…Only genes with average TPM ≥ 1 / sample (i.e., the sum of 12 TPM values in 12 samples in each group TPM sum ≥ 12; referred to as filtered background) were analyzed further. Differential expression between all Ctrl and SCNx samples was analyzed by DESeq2 using RNAlysis 3.8 GUI [ 39 ].…”

“…The cluster maps reinforce the presence of DEGs unique to each sample, and the potential effects of treatment on the DEGs. Gene set enrichment analysis for the mouse and human mapped genes was performed, using the KEGG7 database 50 (www.kegg.jp) and RNAlysis software 51 to identify the biological pathways that are significantly associated with each sample, and to assess the influence of treatment. We considered KEGG terms with p-adj < 0.05 as significant enrichment.…”
