NgsAdmix

NGSadmix

Infer the ancestry proportions from low depth NGS data. The principal is the same as other softwares such as FRAPPE and ADMIXTURE however, ngsAdmix also works when you have uncertainty in your data. This makes it ideal for medium and low depth sequencing data where many genotypes cannot be called without introducing errors or ascertainment bias.

NgsRelate

A software package for inferring relatedness and inbreeding between pairs of individuals from NGS data. This is a new version.

Relate

Relate. Infered IBD sharing across a chromosome for a sib pair estimated using affy 500k data

This method estimates the probability of sharing alleles identity by descent (IBD) across the genome and can also be used for mapping disease loci using distantly related individuals. To accommodate LD the methods need SNP for several individuals in order to estimate the allele frequencies and the pairwise LD. The method return the posterior probabilities of the IBD states across the genome and the overall IBD sharing.

RelateAdmix

A software package for inferring relatedness between pairs of individuals even if the individuals are admixed.

CATS

joint power of a non-symetric two stage GWA design

R package for power estimation for a two-stage genome-wide association design. This is a modification of the code from Skol et al 2006, nat genet. so that the relative risk, case-control ratios and allele frequencies are allowed to vary between stages.
