2.4 Pedigree file

The input pedigree file may contain parameter statements at the start. It is convenient to have statements which describe the contents and format of the pedigree file in the file itself, rather than in parameter files. The pedigree file contains two parts, the parameter statement part, terminated by the file separator `****', and the pedigree data part.

The pedigree data consists of one line for each individual. Each line begins with three names, followed by integers, then real numbers. The numeric data is not required in all cases. This format is specified in the `input pedigree record names 3 integers...' statement.

The first three fields in each line consist of required data: the names of the individual and her or his parents. The names can be up to 12 alphanumeric characters. Founders, however, have parents with names `0 0'. Gender, if present, is the fourth item. These three or four items may be followed by an "observed" indicator, with values of `0' indicating unobserved individuals, `1' indicating observed individuals. Other integers, if present, follow this, then real numbers, if present.
