Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 As shown, the high-efficiency parallel computing and high-accuracy genome-wide selection method of the present invention is characterized in that it comprises the following steps:
[0038] Step 1: read the original genotype file and the original phenotype file, extract the genotype data and phenotype data of the same individual in the original genotype file and the original phenotype file, and form a new genotype file and a new phenotype file, And use the new genotype file to calculate the kinship matrix G among all individuals.
[0039] In this embodiment, the S4 data format in the R language is used to establish the data mapping between the disk and the internal memory; the reading and storage of the genotype file and the phenotype file adopt the big.matrix format in the R CRAN::bigmemory software package , and provi...
