2.5 Pedigree file description statements

allow pedigree size N

This statement overrides the program-defined maximum pedigree size (presently 20,000 individuals).

input pedigree size N

Here, N is the number of records to be read. It may be less than the actual number of individuals in the pedigree file.

input pedigree record names 3 [integers I] [reals J]

This specifies the numbers of entries in each line of the pedigree file. There must be three names (up to 12 alphanumeric characters each) for the individuals and parents. Optional integers include gender and phenotypic or discrete trait data. Real numbers could be covariates or quantitative traits.

input pedigree record (father mother | mother father)

This statement specifies the order of parental names. `father mother' is the default.

input pedigree record gender (present | absent)

Gender, which follows the triplet of names is optional. If this statement is not included, the default is `gender present'. Gender is coded as an integer, such that `1' is male, `2' is female and `0' is unsexed.

input pedigree record traits K1 K2... integers I1 I2...

This statement is needed when there is integer data for traits, and the data for traits does not immediately and consecutively follow gender (if present). Use this statement to specify the correspondence between integers in the record and trait numbers.
