SRmapqtl is part of the QTL Cartographer suite of programs.

SRmapqtl uses stepwise regression to map quantitative trait loci to a map of molecular markers. It requires a molecular map that could be a random one produced by Rmap, or a real one in the same format as the output of Rmap.

This program should be run before Zmapqtl if you want to use composite interval mapping.
