MATLAB 7.X 生物信息工具箱的应用-- 专用分析工具（ 六）*

序列分析可以获取蕴藏在简单序列中的生物信息,是生物信息分析的基础。通过生物大分子序列差异分析构建的系统树则可为我们提供可视化的物种间的进化关系。MATLAB7.X生物信息工具箱包含了几个图形用户界面设计的专用分析工具,这些专用分析工具交互性好,易于使用。借助于这些分析工具,用户不仅可以对基因序列进行分析查看并能进行相对应的氨基酸序列分析,还可以方便快捷地构建系统发育树。即使用户不会编程也可以进行序列分析和系统发育分析的研究,大大地提高了分析的效率。本文详细介绍了序列分析工具Seqtool和系统发育分析工具Phytreetool在序列分析及系统发育树构建方面的应用,所有操作方便快捷,分析结果可视化程度高。

The Application of MATLAB Bioinformatics Toolbox --Special Analysis Tools (6)*

Sequence analysis is the basis of Bioinformatics analysis,which can obtain the information embedded in the simple sequence.The phylogenetic tree,constructed by sequence analysis of biological macromolecules,can provide us with visible evolutionary relationship among species.The MATLAB7.X bioinformatics toolbox contains several special analysis tools designed by graphic user interface(GUI),which have the advantages of good interactivity and convenience to use.With these tools,you can achieve all analytic functions without the commands,improving analytic efficiency greatly.This paper introduces sequence tool-Seqtool and phylogenetic tree tool-Phytreetool in the field of sequence analysis and the construction of phylogenetic tree.All the operations are sample and effi-cient,with high degree visualization.
