A Mixed Population Analysis can be started in two ways, either by right clicking on the Mixed Population Analysis folder in the study explorer and selecting New, or by going to the Analysis menu and selecting New and then Mixed Population Analysis. When a new Mixed Population Analysis is selected, the user is required to first enter a Name for the analysis and an optional Description. The Mixed Population Analysis editor will not allow further edits by the user until the name is defined. Once a Name is entered, the DSS File Name and Report File will automatically be filled out. The DSS filename is by default a DSS file with the same name as the analysis. The report file is given the same name as the analysis with the extension ".rpt". The Mixed Population Analysis editor is shown in the figure below.
