Windows QTL Cartographer 2.5
AIC ---> c(n) = 2
BIC-M1 ---> c(n) = 2ln(ln(n))
BIC-M2 ---> c(n) = 2ln(n)
BIC-M3 ---> c(n) = 3ln(n)
BIC-X ---> c(n) = 10*X*ln(n)
Score - 0.05 significant level
Score - 0.10 significant level
Score - 0.20 significant level
Score - X significant level
Note: The first 6 options are BIC search criteria. BIC = n*ln(Q*Q)+p*c(n)
n: sample size, Q*Q: residula varance of model, p: regressor (marker) number
Choose last 4 options (Score), WinQTLCart will use score statistics (not LR) to do the forward
search for both main and epistatic QTLs as initial MIM model.
2. Click the spin dial beside MIM walk speed in cM to select the walk speed. The smaller the
number, the more precise the model, but the longer the analysis will take. (We recommend
accepting the default value.)
3. Click OK. WinQTLCart builds the model based on the trait and the model parameters you
selected. Under the Cancel button in the form, WinQTLCart displays its progress as it works
through the file. The process may take several minutes or several hours, depending on your data.
You can safely minimize the WinQTLCart window and work on other apps in the foreground.
4. The MIM form redisplays with the buttons enabled, the Parameters group fields populated, the
new model available in the drop down list, and the model values on the right . The Parameters
fields are now populated.
Note To see the entire model without scrolling, click the blue button.
Where to go from here
From here, you can refine the MIM model 70 , manually edit the model by clicking the Add QTL and Del
QTL buttons, or click in the model field to change the value of Position, Chromosome, Additive, or
epistatic values. Click Save Model… to save the model as a .MDS file.

After you've specified the model and criteria for the search, the model and its values are loaded into the
MIM form. At this point, you can further refine the model. From the MIM form, click Refine Model to
display the Refine MIM Model dialog.
