Description
QTL mapping in a mixed model framework with separate detection and
localization stages. The former detects the number of QTL on each chromosome
based on the genetic variation due to the grouped markers on the chromosome,
while the latter stage uses this information to determine the most likely QTL
positions. The mixed model can accommodate general fixed and random effects,
including spatial effects in field trials and random pedigree effects.

Package: dlmap
Type: Package
Version: 1.13.1
Date: 2013-12-11
License: GPL 2
The function dlcross is a constructor function for dlcross
objects to be input to dlmap.
It will read in files in several different formats, including the qtl
cross format and two new formats to
accommodate association mapping populations and designs with extensive
phenotypic data.
The primary function is dlmap, which performs the iterative
algorithm to detect and position QTL on all chromosomes with significant
genetic variation. This can accomodate sophisticated mixed models for phenotypic
variation in addition to the genetic modeling.
Because ASReml-R is proprietary, we provide the option of using the nlme package to fit mixed models via the algorithm argument. However, there
are some features which are only accessible when the algorithm used is asreml.
The vignette included in this package gives more background on the methodology, input file structure, and examples of how to use each of the important functions
in the package.
