Hi

I am doing pedigree analysis (linear linkage analysis ) for polygenic diseases such as obesity, hypertension in parent-children. I have seen the tutorial video and manual, but I am not sure how to input the parent's phenotype.
My research data does not contain genetic information, only the phenotype.

I'm wondering if there is a way to put the parent's phenotype (categorical variables like with disease vs. without disease) in the pheno file.

Thank you.
