Software
Professor Loïc Yengo has developed a range of software tools associated with the various research studies in which he has participated. These tools are listed below and are listed in his GitHub page.
Yengo et al. (2025) [in prep.]. Within-family heritability estimates from 500,000 sibling pairs of diverse ancestries.
- ConvertFSIR. This is an R-based function that converts within-family sibling regression (Visscher et al., Plos Genet. 2006) estimates of heritability and shared-environmental variance for binary traits (e.g., disease) from the observed 0-1 scale to an underlying continuous liability.
Wainschtein et al. (2025) [under review]. Estimation and mapping of the missing heritability of human phenotypes.
- rseREML. This is an R-based function to estimates heritability of quantitative traits using pedigree data available in large biobanks. The code is optimized for large sample sizes and relatively small family sizes.
- fastGREML. This is a C++ program that implements computational improvements to the GREML methodology initially implemented in GCTA. It notably relies on stochastic approximation.
- predLink. This C++ program predicts genetic linkage from summary statistics of genome-wide association studies.
- Related theory and codes can be found here.
- simAM. This C++ code simulates samples of genotypes and phenotypes from a population undergoing assortative mating.
- makeDGRM. This C++ code generates a Disequilibrium Genomic Relationship Matrix from individual-level genotype data in PLINK format.
- makeBCDGRM. This C++ code generates Disequilibrium Genomic Relationship Matrix from a set of pre-calculated standard Disequilibrium Genomic Relationship (in GCTA format) Matrix per chromosome.
