Form Linkage Groups

Select menu: Stats | QTLs (linkage/Association) | Map Construction | Form Linkage Groups

Use this to form linkage groups for markers.

After you have imported your data, from the menu select
Stats | QTLs (linkage/Association) | Map Construction | Form Linkage Groups.
Fill in the fields as required then click Run.

You can set additional Options before forming groups and Store the results.

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 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.

Marker names

A text specifying the names for each marker.

Parent information

The parent information should be supplied within a pointer to a set of texts (one for each parent).

Type of population

A list of population types. Select as follows:

F2 for an F2 population
BC1 for a backcross population
DH for a double-haploid population
RILn for a population of recombinant inbred lines
CP for outcross populations.
