Abstract:
目的:开发一套能高效准确地从GWAS Catalog公开数据库中筛选全基因组关联研究(GWAS)的R脚本。 方法:参考既往研究制定GWAS的筛选原则。将人工在GWAS Catalog的筛选过程抽象为标准的算法,2名程序员共同撰写R脚本(gwasfilter.R)后,由他人多次对脚本进行测试。 结果:采用gwasfilter.R筛选GWAS包含6个步骤。该脚本内置5个主要函数,可以同时根据“是否有验证人群”“样本量大小”和“研究人群种族”等条件对GWAS进行筛选。筛选单个性状时,程序用时不超过1秒。 结论:gwasfilter.R操作简便,筛选过程高效而标准化,可灵活应用于GWAS筛选。脚本源代码网址:https://github.com/lab319/gwas_filter。
