Browse to the layout file and open it:
Click Continue to read the layout file and you will open a trait mapping form. Nearly all the traits have been automatically mapped to variables in the ontology because they have exactly the same names. You should check each to be sure the automatic mapping is correct. Any variables which cannot be mapped remain in the Un-mapped variables box.
In our case GYGP – grain yield in grams per plot has not been mapped. It should be mapped to the variable GrYld_wgh_gplot. To make this mapping drag the variable down and place it in the Traits section then click Apply Mapping.
This will open the Ontology search box. Look for grain yield traits and select GrYld_wgh_gplot.
Now the mapping is complete click Next.
You will get a review panel to check the import:
Click Finish and the design (and data in our case) will be stored.
Add trait GYTHA if necessary and compute its values for all locations. We will use this variable for statistical analysis.
