Assessment of genotype imputation methods
Several methods have been proposed to impute genotypes at untyped markers using observed genotypes and genetic data from a reference panel. We used the Genetic Analysis Workshop 16 rheumatoid arthritis case-control dataset to compare the performance of four of these imputation methods: IMPUTE, MACH, PLINK, and fastPHASE. We compared the methods' imputation error rates and performance of associa...
متن کاملA Flexible and Accurate Genotype Imputation Method for the Next Generation of Genome-Wide Association Studies
Genotype imputation methods are now being widely used in the analysis of genome-wide association studies. Most imputation analyses to date have used the HapMap as a reference dataset, but new reference panels (such as controls genotyped on multiple SNP chips and densely typed samples from the 1,000 Genomes Project) will soon allow a broader range of SNPs to be imputed with higher accuracy, ther...
متن کاملNext Generation Altimeter Service
The Radar Altimeter Database System RADS was launched by DEOS in 2001 as a precursor to an operational observing system as envisaged by the upcoming International Altimetry Service IAS. It is a facility to easily manage and access calibrated and validated altimeter data with consistency as common denominator. Whenever new data, models or knowledge arrive, the system is updated. We have now over...
متن کاملMethods for Multimedia Service Adaptation in Next Generation Networks
In Next Generation Networks (NGNs), vertical handovers between different wireless access technologies provide seamless roaming during active multimedia sessions. The quality of these multimedia sessions, as well as the quality of user experience, depends on the network handover policies, link layer characteristics, and codecs used in the respective networks. Even though extensive research has b...
متن کاملGenotype imputation.
Genotype imputation is now an essential tool in the analysis of genome-wide association scans. This technique allows geneticists to accurately evaluate the evidence for association at genetic markers that are not directly genotyped. Genotype imputation is particularly useful for combining results across studies that rely on different genotyping platforms but also increases the power of individu...
