摘　　要：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/gwasfilter。Objective To develop an R script that can efficiently and accurately filter genome-wide association studies(GWASs)from the GWAS Catalog Website.Methods The selection principles of GWASs were established based on previous studies.The process of manual filtering in the GWAS Catalog was abstracted as standard algorithms.The R script(gwasfilter.R)was written by two programmers and tested many times.Results It takes six steps for gwasfilter.R to filter GWASs.There are five main self-defined functions among this R script.GWASs can be filtered based on"whether the GWAS has been replicated""sample size""ethnicity of the study population"and other conditions.It takes no more than 1 second for this script to filter GWASs of a single trait.Conclusions This R script(gwasfilter.R)is user-friendly and provides an efficient and standard process to filter GWASs flexibly.The source code is available at github(https://github.com/lab319/gwas_filter).
