Introduction

The recent advent of Next Generation Sequencing (NGS) techniques, has enabled transcriptome-scale analysis of the RNA epistructurome. Despite the establishment of several methods for querying RNA secondary structures (CIRS-seq, SHAPE-seq, Structure-seq, DMS-seq, PARS, SHAPE-MaP, DMS-MaPseq), and RNA post-transcriptional modifications (Ψ, m¹A, m⁶A, m⁵C, hm⁵C, 2'-OMe) on a transcriptome-wide scale, no tool has been developed to date to enable the rapid analysis and interpretation of this data.

RNA Framework is a modular toolkit developed to deal with RNA structure probing and post-transcriptional modifications mapping high-throughput data.
Its main features are:

• Automatic reference transcriptome creation
• Automatic reads preprocessing (adapter clipping and trimming) and mapping
• Scoring and data normalization
• Accurate RNA folding prediction by incorporating structural probing data
