Rcirc: an R package for circRNA analyses and visualization

Circular RNA (circRNA), which has a closed-loop structure, is a kind of special endogenous RNA and plays important roles in many biological processes. With the improvement of next-generation sequencing technology and bioinformatics methods, some tools have been published for circRNA detection based on RNA-seq. However, only a few tools focus on downstream analyses, and they have poor visualization ability. Here, we developed the R package ‘Rcirc’ for further analyses of circRNA after its detection. Rcirc identifies the coding ability of circRNA and visualize various aspects of this feature. It also provides general visualization for both single circRNAs and meta-features of thousands of circRNAs. Rcirc was designed as a user-friendly tool that covers many highly automatic functions without running many complicated processes by users. It is available on GitHub ( https://github.com/PSSUN/Rcirc ) under the license GPL 3.0.
