Estimate the genetic relationship matrix (GRM) between pairs of individuals from a set of SNPs and save the lower triangle elements of the GRM to binary files, e.g. test.grm.bin, test.grm.N.bin, test.grm.id.
結果會生成矩陣的下三角,保存為二進制文件。
「Output file」
test.grm.bin (it is a binary file which contains the lower triangle elements of the GRM). 這個是二進制存儲的GRM
test.grm.N.bin (it is a binary file which contains the number of SNPs used to calculate the GRM). 這個是二進制文件,存儲的是參與計算的SNP個數(shù)
test.grm.id (no header line; columns are family ID and individual ID, see above).
這個是FID和IID的信息。
Estimate the GRM, save the lower triangle elements to a compressed text file (e.g. test.grm.gz) and save the IDs in a plain text file (e.g. test.grm.id). 估計的GRM文件,存儲矩陣的下三角,壓縮文件,存儲ID信息
「Output file format」test.grm.gz (no header line; columns are indices of pairs of individuals (row numbers of the test.grm.id), number of non-missing SNPs and the estimate of genetic relatedness) 生成的文件,為壓縮文件,第一列和第二列為編號信息(根據(jù)ID的順序編號,相當于是矩陣的下三角行列信息),第三列是SNP個數(shù),第四列是相關系數(shù)
