Version 0.44

qtl2 0.44 (2026-07-06)

New features

• Added a general genome scan function scan1gen which takes as input an R function that calculates the log10 likelihood.

• Added ability to use scan1perm with an alternative scan function such as scan1gen or scan1snps.

Minor changes

• Potential speed-up of scan1() and scan1perm(): the eigen library has implemented least squares regression with multivariate outcomes.

• For parallel computing, use of cores=0 argument now results in all but one core (parallel::detectCores()-1) rather than all cores.
