The
Compare QTL Plots
provides a quick and easy method for comparing results from multiple analyses. Output data sets from the

QTL IM, CIM and MIM Analysis
process are merged into one data set containing

variables
from the specified studies. The

QTL Test Size
and

QTL Effect Size
variables in the merged data set are overlaid on a single plot to facilitate the comparison of

QTL
mapping results from different methods and/or

traits
.

At least two
Input SAS Data Set
s are required. These include one

Base Input SAS Data Set
and at least one or as many as twelve

Merge Input SAS Data Set (1-12)
. Both must contain containing

Testing Location
variables and

QTL Test Size
variables obtained from the

QTL IM, CIM and MIM Analysis
process.

The
qtlsf_im.sas7bdat
base input data set is shown below:

In this data set,
CM
serves as the Key Testing Location variable and

LOD1
and

LOD2
serve as the Test Size variables.

The
qtlsf_cim.sas7bdat
merge input data set is shown below:
