A demo dataset of genotype and phenotype for ALGWAS

The genotypic file requires a header row, which shows the names of individuals. The first row shows the names of molecular markers or SNPs. For each SNP, the genotypes, e.g., AA, AT, TT, are required to transformed to integer format as 0, 1 or 2 based on allelic frequency. For example, A is the major allele that AA and TT will be transformed to 0 and 2, the AT is transformed to 1. It means the copy number of minor alleles for a line at a SNP locus, relative to major allele. The phenotype file must contain a header row, which represents the names of traits. The first column shows the names of the individuals (Table 2). The trait values are numeric and missing values are indicated as NA, following the R coding requirement.
