QTL Cartographer is a suite of programs for mapping quantitative trait loci
(QTLs) onto a genetic linkage map. The general experimental paradigm begins
with a pair of inbred parental lines that differ in the trait of interest and in
the set of marker genotypes. The programs use linear regression, interval
mapping or composite interval mapping methods to dissect the underlying
genetics of the quantitative traits. Mapping is done onto a set of linked
genetic markers with known recombination frequencies. The mapping program uses
a dynamic algorithm that allows a host of statistical models to be fitted and
compared. The package consists of several programs written in C to perform
various tasks, including simulating, reformatting or analyzing data and
visualizing the results of the analyses. The mapping programs can handle data
from backcrosses, intercrosses and recombinant inbreds, as well as a few other
experimental designs. The source code and compiled binaries are freely
available and may be obtained by through our web page
