Data obtained from the hapmap project and pre-processed by CRLMM to produce genotype calls. Due to size limitations, we only included every 10th SNP from the Affy's 50k Xba chip. 'Copy number' estimates were obtained from using the calculate copy number function in the oligoClasses package and is used solely to illustrate properties of the classes defined in SNPchip. Better approaches for estimating copy number are available in other packages, and currently under development in the oligo package.
从HapMap计划中获得的数据和前处理由CRLMM生产基因型分型。由于规模的限制,我们只包括Affy的50K XBA芯片每10单核苷酸多态性。 “拷贝数的估计获得使用在oligoClasses包计算拷贝数功能,仅用于说明在SNPchip定义的类的属性。估计拷贝数的更好的方法可以在其他包,以及目前正在发展中的寡核苷酸包。
