The documentation states that in a pedigree file, the first column is family ID, second is pro band ID, third is father ID, and fourth is mother ID. But what is actually separating the ID numbers?
For example, lets say that I have these samples: proband = 1000 father = 1000-01 mother = 1000-02
In this case, would the family ID be 1000? This would mean the pro band ID would be 0? and would the father ID be 01 or would it be -01?
Thanks so much for your help.
