PLINK - error in --make-bed

Question

[bsmith030465]

Hi,

I was trying to convert my ped file to a bed file with the command

plink --file mysamples --make-bed

However, I get the error:

 Scanning .ped file...
 Possibly irregular .ped line.  Restarting scan, assuming multichar alleles.

 Error: Half-missing call in .ped file at variant 1, line 1.

The first line of my ped file (testing with only 15 variants) is:

FES2356 ES1249 0 0 1 1 1 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 0 1 1 1 0 1 0 1 0

Where am I going wrong?

thanks!

‘0’ is normally the missing-genotype code. The body of a .ped line is supposed to look like “A C A A T G ...”.
