This software has several features: Handle complicated genetic models for agronomic traits, seed traits, and developmental traits; Analyze unbalanced data; Combine jackknifing techniques to test the significance of each genetic parameter; Some important references are listed in the result files. Models and formulas in this software package are given in Zhu (2001). Kernel for these models including Agronomy model, Animal model, Seed model, Sex model, Trial model, and QTL Data model was written by Jun Zhu,Link Map model was written by Jixiang Wu, Germplasm model was developed by Haiming Xu, Microarray model was developed by Yan Lu; The graphic user interface was developed by Guobo Chen and Zhixiang Zhu.

How to run the program:
Six
steps to run an input file
1.Create
an input file Regular
text file editors, include the QGAStation can be used for preparing input
files. But using Microsoft
Excel,
or other electronic table software can make it much easier to prepare and
manage your input files. Each method employs different file formats. You
could find data formats definition in the help document of each method,
and we also provide some samples of input files under the
Sample folder. Missing
data is denoted by dot (".").
2.Open
an existent files You
could open an input file through main menu [File]>>[Open], or click [Open] icon on the toolbar to open a file including raw
data.
3.Select
analysis method and model An
input file should be analyzed by a model using appropriate statistical
methods. Select a model through menu [Method],
which lists different methods collected in QGAStation, including Agronomy methods, Animal methods, Seed methods, Trial methods and Link
Map method. Click one of selection in Method menu, a submenu will pop
out, which lists various models along with a certain statistical methods.
Now, you could select a method and a model you want from the
submenu.
4.Coefficient
setting A Coefficient-setting
Box will pop out when you have selected a certain model from [Method].
You could find the details about meaning of each coefficient in help
documents of every model selected.
5.Run After
setting the coefficients, you could Run the input data with set coefficients through Run button at the bottom of Coefficient-setting Box, or exit the
Coefficient-setting Box without running through click the Cancel button ,which also is at the right of the Run
button.
6.View
the result files The
result files will be saved under the same direction of input file. Because
all result files are text files, you could view the result files with any
kind of text viewer, of course, electronic table software such as
Microsoft excel is much better to view the result files .In every result
file, data are separated by commas in every line.
Note: One file will be automatically created, named filename.cgb, which saves the filtered observation(s) containing missing data.
