Add --no-fid, --no-parents, --no-sex, and --no-pheno to your plink command line.

hello sir, actually i am having SNP data in hapmap format generated by GBS (crop=maize), i converted the hap to .ped  and .map format. the ped form as usually has six column with missing FID,parents, SEX, phenotype. In these regard when i tried calculate allel frequency on chromosome wise, the out put says scaning 0 of 0 chr. (maize chr no is 10)

ex : ERROR: Problem with MAP file line:
           1    S1523360    0    523360

2. here the phenotyping data is taken from field for quantitative traits, how can go for case/control for data. has there is no controls. suggest me the input format or command line for this situation
