anexVis: visual analytics framework for analysis of RNA expression

Summary: Although RNA expression data are accumulating at a remarkable speed, gaining insights from them still requires laborious analyses, which hinder many biological and biomedical researchers. This report introduces a visual analytics framework that applies several well‐known visualization techniques to leverage understanding of an RNA expression dataset. Our analyses on glycosaminoglycan‐related genes have demonstrated the broad application of this tool, anexVis (analysis of RNA expression), to advance the understanding of tissue‐specific glycosaminoglycan regulation and functions, and potentially other biological pathways. Availability and implementation: The application is accessible at https://anexvis.chpc.utah.edu/, source codes deposited on GitHub. Supplementary information: Supplementary data are available at Bioinformatics online.
