I want to start with the quality control of my data, but some files are not complete I think;
I have received this PED file (please see attached) https://ibb.co/029NR33 but I do not see all information that should be in:
FID, IID, PID, MID,SEX,PHENO
How can I change that?
Do you think that this form is a PED file? Or did they give it a wrong name?
