In the eXpresseXpress Model topology export format, the Dependencies column contains the abbreviation of one or more input ports that are dependencies of the output function(s) listed in the Function column. The input ports listed in this column must be listed in the Port column and, if the Port Flow column is used, the flow direction must not be set to "output." For automatic functions (ports with no value in the Function column), the values in the Dependencies column will be ignored (since automatic functions always have default dependencies). In the sample spreadsheet below, notice how multiple dependencies are listed in cell E15. Also, notice how dependencies are not specified for the automatic functions specified in rows 3, 6, 8, 10,12 and 18.
