Features

GLIMPSE2 is a set of tools for phasing and imputation for low-coverage sequencing datasets:

• GLIMPSE2_chunk splits the genome into chunks for imputation and phasing
• GLIMPSE2_split_reference creates the reference panel representation used by GLIMPSE2_phase. It allows major speedups for large reference panels.
• GLIMPSE2_phase program to impute and phase low coverage sequencing data
• GLIMPSE2_ligate concatenates phased chunks of data into chromosome-wide phased files

GLIMPSE1

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 and checkout the GLIMPSE1 branch.

Building from source

GLIMPSE2 supports Linux x86_64, Linux aarch64, and macOS ARM64 (Apple Silicon).
