目录 说明 实战 说明 Admixture通过EM算法一般用于指定亚群分类:或者在不知材料群体结构背景下,通过迭代交叉验证获得error值,取最小error对应的K值为推荐亚群数目.如果我们预先已知群体的类型(百分百确信),那么可以考虑监督分类方法,设置标签,提高分群的准确性. Admixture目前是1.3.0,文档也刚更新不久. 怕翻译有误,贴上官方文档: Estimating P and Q from the SNP matrix G, without any additional inf
一般来说有两种解决方案. 第一种:添加“--plink-tped”参数: 用vcftools的“--plink”参数生成plink格式文件时,小样本量测试可以正常生成plink格式,用大样本量时产生Writing PLINK PED and MAP files ... Error: Could not open temporary file.报错,于是尝试将“--plink"参数修改为”--plink-tped“参数,成功运行,具体如下: /bin/vcftools --vcf 1000Gen
实验材料 构建的群体,或自然群体,如各地方品种. RAD文库构建 提取DNA后,构建文库,简要步骤如下: ① 限制性内切酶TaqI酶切: ② 连接P1接头: ③ DNA随机打断片断化: ④ 目的片段回收与末端修复: ⑤ 连接P2接头: ⑥ RAD片段富集: ⑦ 上机测序. 参考:Rapid and cost-effective polymorphism identification and genotyping using restriction site associated DNA (RAD
