If data structure names have been stored in a QTL data space then when the QTL menus are opened the data structure names will automatically be entered into the relevant fields. Also 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.
