简介:高产量的genotyping芯片为极大地作出贡献到为复杂疾病发现危险性基因的染色体宽的协会研究(GWAS)生产了巨大的数据集。为为GWAS执行数据分析有二策略。一策略是使用为GWAS被设计的公开源码或商业的包裹。其它将与特定的功能利用经典基因程序,例如连接不平衡印射,haplotype推理和传播不平衡测试。然而,可得到的很经典的程序不对直接分析芯片数据合适并且要求定做的输入,它导致把未加工的genotyping文件变换成各种各样的数据格式的不方便。我们开发了一个强大的、用户友好的、小节目为包括五个主要模块(变压器,操作员,预览器,编码者和模拟器)的GWAS的命名SNPTransformer。为把genotyping文件转变成十输入的工作不仅与经典遗传包裹为使用格式化,而且执行的工具箱有用函数象标志上的关系操作那样,预览数据文件,重新代码数据格式和模仿的标记文件,在另外的函数之中。它为人的遗传学者作为一个在里面手工具箱用下游地基因的节目,和罐头行为衔接在上游的未加工的genotyping数据,特别为非程序员。SNPTransformer在http://snptransformer.sourceforge.net是自由地可得到的。
