The comparative linkage results of the chromosome 1 of the family 5026.10 using CompareLinkage and dChipLinkage. The genotype calls are displayed on the left in yellow (AB), red (AA) and blue (BB), with SNPs on rows and samples on columns. The sample names and the disease status (1 = Unaffected and 2 = Affected) are displayed on the top. The linkage scores of different software are displayed on the right in the shaded box. The lower and upper limits of the shaded box (such as [-10, 6]) are in the brackets on the bottom of the curve. The red vertical line indicates the threshold of 3.0 for LOD scores and 3.7 for NPL scores. This line is user adjustable.
