Zmapqtl uses composite interval mapping 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. The sample could be a randomly generated one from
Rcross or a real one in the same format as the output of
Rcross. In addition, the program requires the results of the stepwise linear regression
analysis of SRmapqtl for composite interval mapping.
