3.1 Introduction to pedcheck

pedcheck reads the pedigree file and checks for errors in the pedigree structure. Specifically, the following errors are checked for:

If no errors are found, pedcheck reports the number of component (connected) pedigrees found and lists for each component:

If there are changes to the file, pedcheck writes an output pedigree file. Requested changes may include reordering of the pedigree chronologically, the addition of gender, the addition of an observed indicator, and reversing the order of the parental names.

Other MORGAN programs do their own pedigree checking by calling the relevant pedcheck functions, but it is still useful to do preliminary processing of data files first.
