We launch a webserver for RNA structure prediction and design corresponding to tools developed using our RNA-As-Graphs (RAG) approach. RAG uses coarse-grained tree graphs to represent RNA secondary structure, allowing the application of graph theory to analyze and advance RNA structure discovery. Our webserver consists of three modules: (a) RAG Sampler: samples tree graph topologies from an RNA secondary structure to predict corresponding tertiary topologies, (b) RAG Builder: builds three-dimensional atomic models from candidate graphs generated by RAG Sampler, and (c) RAG Designer: designs sequences that fold onto novel RNA motifs (described by tree graph topologies). Results analyses are performed for further assessment/selection. The Results page provides links to download results and indicates possible errors encountered. RAG-Web offers a user-friendly interface to utilize our RAG software suite to predict and design RNA structures and sequences.
The webserver is freely available online at: http://www.biomath.nyu.edu/ragtop/.
Supplementary data are available at Bioinformatics online.
我们推出了一个用于 RNA 结构预测和设计的网络服务器，该服务器对应于我们使用 RNA-As-Graphs (RAG) 方法开发的工具。RAG 使用粗粒度的树图来表示 RNA 二级结构，允许应用图论来分析和推进 RNA 结构发现。我们的网络服务器由三个模块组成：(a) RAG Sampler：从 RNA 二级结构中采样树图拓扑结构，以预测相应的三级拓扑结构，(b) RAG Builder：从 RAG Sampler 生成的候选图中构建三维原子模型，以及 (c) RAG Designer：设计折叠成新 RNA 基序（由树图拓扑结构描述）的序列。结果分析用于进一步评估/选择。结果页面提供了下载结果的链接，并指出可能遇到的错误。RAG-Web 提供了一个用户友好的界面，可用于利用我们的 RAG 软件套件来预测和设计 RNA 结构和序列。
该网络服务器可免费在线使用：http://www.biomath.nyu.edu/ragtop/。
