qtl2fst

R/qtl2 (aka qtl2) is a reimplementation of the QTL analysis software R/qtl, to better handle high-dimensional data and complex cross designs.

The qtl2fst package uses the fst package to store genotype probabilities in a set of files for rapid access but reduced memory usage. It is fully integrated with R/qtl2, and is modeled after the qtl2feather package which stores files in the feather format.
