Although the R platform and the add-on packages of the Bioconductor project are widely used in bioinformatics, the standard task of multiple sequence alignment has been neglected so far. The msa package, for the first time, provides a unified R interface to the popular multiple sequence alignment algorithms ClustalW, ClustalOmega and MUSCLE. The package requires no additional software and runs on all major platforms. Moreover, the msa package provides an R interface to the powerful package shade which allows for flexible and customizable plotting of multiple sequence alignments.
msa is available via the Bioconductor project: http://bioconductor.org/packages/release/bioc/html/msa.html. Further information and the R code of the example presented in this paper are available at http://www.bioinf.jku.at/software/msa/.
尽管R平台和生物导体项目的附加软件包在生物信息学中被广泛使用,但到目前为止,多序列比对的标准任务一直被忽视。msa软件包首次为流行的多序列比对算法ClustalW、ClustalOmega和MUSCLE提供了统一的R接口。该软件包无需额外的软件,可在所有主流平台上运行。此外,msa软件包为功能强大的shade软件包提供了R接口,该软件包允许对多序列比对进行灵活且可定制的绘图。
msa可通过生物导体项目获取:http://bioconductor.org/packages/release/bioc/html/msa.html。本文中示例的更多信息和R代码可在http://www.bioinf.jku.at/software/msa/获取。
