A list of two objects named pedigree and genotypes:

  1. pedigree is a data frame with the following information:

    1. Family ID

    2. Isolate ID

    3. Paternal ID. This is not used by XIBD and is set to zero.

    4. Maternal ID. This is not used by XIBD and is set to zero.

    5. Gender - 1 for male and 2 for female

    6. Affection status of individuals. This is set to 2 and is ignored by XIBD IBD inference.

  2. genotypes is a data frame with the first 11 columns:

    1. Chromosome

    2. SNP identifier

    3. Genetic map distance

    4. Base-pair position

    5. Population allele frequency

    6. Condition SNP number

    7. Conditional probability Pr(ba)

    8. Conditional probability Pr(bA)

    9. Conditional probability Pr(Ba)

    10. Conditional probability Pr(BA)

    11. Allele frequency of conditioned SNP

    where each row describes a single SNP. Columns 12 onwards contain the genotype data for each individual, where a single column corresponds to a single individual. These columns are labeled with merged family IDs and individual IDs separated by a slash symbol (/).
