A: Once the *.gat file is loaded into the Attribute Manager the saved colour/shape/size groups are displayed under each tab.  To attribute the data using these settings select the Colour tab and then select the correct column that contains the entries listed under the Colour tab and click on the Auto-Attribute button.  When asked whether to use a New colour scheme or the Existing one click on the Existing button.  The data points should be then updated with the saved coloured and the row information updated for each group as well.  Repeat this process for the Shape and Size tabs.
