Additional file 6 of On the impact of relatedness on SNP association analysis

Sample selection of HapMap genotype data. This file provides annotations for 174 HapMap CEU samples. The columns FID (family identifier), IID (individual identifier), dad, mom, sex (1=male, 2=female), pheno (always 0), population (always CEU) correspond to the columns of relationships_w_pops_121708.txt filtered for CEU samples as provided by HapMap. The column ctr contains a unique trio identifier and equals NA when the sample does not belong to a complete trio family. The reason for exclusion is provided where applicable, otherwise NA is stated and the sample is included in our study. (CSV 8 kb)

HapMap基因型数据的样本筛选数据集。本文件为174个HapMap CEU样本提供注释信息，各列分别为：FID（家系标识符，family identifier）、IID（个体标识符，individual identifier）、父亲标识符、母亲标识符、sex（性别，1代表男性，2代表女性）、pheno（表型值，恒为0）、population（人群类型，恒为CEU），上述列均源自HapMap提供的、经CEU样本筛选后的relationships_w_pops_121708.txt文件的对应字段。列ctr包含唯一的三人家系标识符，若样本不属于完整三人核心家系，则该字段取值为NA。若样本存在排除原因，则会予以标注；否则标注为NA，且该样本将纳入本研究。（CSV格式，大小8 KB）
