基本的检查之后,我们可以将sumstats一致化,用于downstream analysis 这一步需要参考的 fasta 以及 vcf 这一步用时较长,这里为了节约时间在过滤后的基础上只一致化chr3 mysumstats.filter_in(eq={"CHR":"3"}) #过滤出chr3 mysumstats.clean( basic_check=False, ref_seq="./human_g1k_v37.fasta", ref_...

vcf2gwasis a Python-built API for GEMMA, PLINK and bcftools performing GWAS directly from a VCF file as well as multiple post-analysis operations. Some of the benefits of this pipeline include: VCF file does not need to be converted or edited by the user ...
方法部分写到 We adopted the case–control GWAS strategy, which was widely used in disease gene mapping for humans30,31, to identify SVs that were substantially associated with different morphotypes ofB. oleracea. Briefly, a GWAS analysis was performed between the case group (individuals belonging to...

一般自然群体,基因型个体的杂合度过高或者过低,都不正常,我们需要根据杂合度进行过滤。偏差可能表明样品受到污染,近亲繁殖。我们建议删除样品杂合率平均值中偏离±3 SD的个体。 ❝我的理解:非自然群体中,比如自交系,杂交种F1,这些群体不需要过滤杂合度。 ❞ ...
