Genotype imputation is a commonly used technique that exploits linkage disequilibrium (LD) to infer missing genotypes in genetic datasets, using a reference panel of subjects with complete observations on a more comprehensive set of SNPs.
Redesigned user interface to improve user experience.
Updated pipeline to v1.1.0. Currently, your CNGB Imputation pipeline will run on an SGX-based trusted execution environment.
