Dear Pasi, I have a population of half-sib trees, but the parental genotypes are not available, and I would like to perform a linkage mapping analysis using this software. Is it possible to do this with such data? If so, how should I structure the pedigree file? I have tried, but I get the following error: Error 520 — Error: No parent(s) in a family CHR:0. Also, can I use a genotype panel coded as 0, 1, 2, or should it be formatted differently? Thank you very much for your help. Best, Esteban
