EHP.R
*Description Estimation of Haplotype frequencies from Pooled DNA samples. This program provides variance estimates for haplotype frequency estimates, it allows several kinds of missing information in the genotype data, it also allows for combined genotype data of different pool sizes. This program can be used for testing haplotype-disease associations in case control studies by calculating the likelihood ratio test: 2 log(likelihood for cases) + 2 log(likelihood for controls) - 2 log(likelihood for case+controls).

HAPLOBLOCK
*Description HAPLOBLOCK provides an integrated approach to both haplotype block identification and haplotype resolution, suitable for high-density SNP data. It is based on a Bayesian Network statistical model which takes account of recombination hotspots, bottlenecks, genetic drift and mutations.

PHASE Video Demo
*Description This program implements a new statistical method for reconstructing haplotypes from population genotype data. v2: (1) the introduction of a new computational approach, resulting in much faster haplotype resolution. (2) the introduction of a new model that allows for recombination and decay of Linkage Disequilibrium (LD) with distance, which results in more accurate haplotype estimates. This model also allows the user to estimate recombination rates, and identify recombination hotspots from population genotype data. (3) the facility to perform a test for haplotype frequency differences between cases and controls. (4) more extensive output summarising the results.

SIMCROSS/SIMWALK
*Description Programs for generating optimal haplotype configurations on general pedigrees using a likelihood-based approach to correctly take intermarker recombination fractions into account. simcross ignores untyped parts of the pedigree, and it uses simulated annealing. simwalk combines simulated annealing with random walk method.
