Computational haplotype inference – XML output of SATlotyper. The XML output of SATlotyper is based on the treelike structure of the result. The root of the tree is marked by the <result> tag. The next level in the tree consists of the original input data (<source>), the scored haplotype (<haplotype>) list derived by bootstrapping (<bootstrapping>) and the calculated alternative inferences of the unphased input data (<haplotypings>). The haplotypings branch contains at least one inference of the original input data (<haplotyping>) with the corresponding most parsimonious set of haplotypes (<haplotypes>) and phased genotypes (<genotypes>) as subelements where a genotype (<genotype>) contains the ploidy-specific number of inferred haplotypes.

Experimental methods. This file describes the experimental methods used for (i) the generation of unphased SNP data from tetraploid potato individuals and (ii) the analysis of haplotype inference by amplicon cloning and sequencing.
