SAIGE-QTL is an R package developed with Rcpp for scalable and accurate expression quantitative trait locus (QTL) mapping for single-cell studies.

The method

• Models repeated and complex data structure, due to multiple cells per individual and relatedness between individuals
• Models discrete read counts
• Is fast and scalable for large data, can test 20k genes, tens to hundreds of cell types, millions of cells, millions of genetic variants
• Can test for the effects of rare variation, for which the single-variant test is underpowered (uses set-based tests instead).

The package takes genotype file input in the following formats

• PLINK (bed, bim, fam), BGEN, VCF, BCF, SAV
