A tool for low-coverage whole-genome sequencing imputation
GLIMPSE2 is a set of tools for low-coverage whole genome sequencing imputation. GLIMPSE2 is based on the GLIMPSE model and designed for reference panels containing hundreads of thousands of reference samples, with a special focus on rare variants.
If you use GLIMPSE in your research work, please cite the following papers:
At the moment, GLIMPSE2 performs imputation only from a reference panel of samples. To use the joint-model, particularly useful for many samples at higher coverages (>0.5x) and small reference panels, please visit the GLIMPSE1 website.
2.0.0is now available! See the CHANGELOG for details.
GLIMPSE2 is composed of the following tools:
- chunk. Tool to phase common sites, typically SNP array data, or the first step of WES/WGS data.
- split_reference. Tool to phase common sites, typically SNP array data, or the first step of WES/WGS data.
- phase. Ligate multiple phased BCF/VCF files into a single whole chromosome file. Typically run to ligate multiple chunks of phased common variants.
- ligate. Tool to phase rare variants onto a scaffold of common variants (output of phase_common / ligate).
- concordance. Program to compute switch error rate and genotyping error rate given simulated or trio data.
GLIMPSE is developed by Simone Rubinacci & Olivier Delaneau.
