To create a new default set of groups: From the Analysis groups window, create the groups you want. Right-click the white background area and select 'Save template'. (Please make sure that you save the template in the default directory suggested by the Save As window). Once you have saved the template, right-click in the 'white' background area again. This time, select 'Select default template'. Select the new template you have just created. This will now be the default setting.
