Form Kinship Matrix

Select menu: Stats | QTLs (linkage/Association) | Genotypic Analysis | Form Kinship Matrix

Use this to form a kinship matrix of coancestries from marker scores. The coefficients of coancestries can be calculated using either the Dice similarity measure or by simple correlation. The kinship matrix can be used within a marker-trait association analysis using bi-allelic and multi-allelic markers.

After you have imported your data, from the menu select
Stats | QTLs (linkage/Association) | Genotypic Analysis | Form Kinship Matrix.
Fill in the fields as required then click Run.

Available data

This lists data structures appropriate to the current input field. Double-click a name to copy it to the current input field or type the name. If data has been stored in a QTL data space then only the data structures present within that data space will be displayed in the Available data, otherwise all the current data within Genstat will be displayed. When data are present within the QTL data space you can right-click on the Available data list to open a shortcut menu where you can change between displaying data only within the data space and all data within Genstat.

Marker genotype scores

A pointer specifying the marker scores. The pointer should contain a set of factors (one for each marker) where each factor contains the labels for the alleles separated by the ‘/’ character.

Labels for genotypes

A text specifying labels for the genotypes used to label the rows (and columns) of the kinship matrix.

Save matrix in

Provides a space to specify the name of symmetric matrix to save the kinship matrix.
