To perform GWAS with GLM model and get the P value of SNPs
MVP.GLM(phe, geno, CV=NULL, priority="speed", genoName=NULL, cpu=2, memo="MVP.GLM")
phenotype, n * 2 matrix
genotype, m * n, m is marker size, n is population size
covariates
speed or memory
name of genotype file, when priority is memory, it is used for attach bigmatrix under windows platform
number of cpus used for parallel computation
a marker on output file name
