SNP information file: contains SNPs information in five columns SNP names, chromosome, position, ancestral and derived allele.
Genotype data file : format with haplotype in row and snps in column (with no header and a haplotype id)
现在我的问题是:存储上述信息SNP,和Genotype data的文件一般是什么格式的?r包里面例子给出的格式分别是.inp和.hap格式,怎么由excel 中的数据转成上述格式
