Genotype Likelihoods IMputation and PhaSing mEthod
Catch a glimpse of your low depth sequencing data
GLIMPSE is a phasing and imputation method for large-scale low-coverage sequencing studies.
Main features of the method:
- Accurate imputed genotype calls. Our method takes advantage of reference panels to produce high quality genotype calls.
- Accurate phasing. GLIMPSE outputs accurate phased haplotypes for the low-coverage sequenced dataset.
- Low-coverage sequencing outperforms SNP arrays. Imputation using low-coverage sequencing data is competitive to SNP array imputation. Results for European and African-American populations are interactively available on the website.
- A cost-effective paradigm. GLIMPSE realises whole genome imputation from the HRC reference panel for less than 1$.
