How to export from CellProfiler to FCS 4 express?

FCS requires a ‘.cpout’ file but how to do it? The manual mentions ‘ExportToSpreadSheet’, but I still don’t see ‘.cpout’ file in my output folder. Anyone can tell me how? Thanks in advance:)

Did you rename the file name setting in ExportToSpreadsheet to have the .cpout extension, as per this page? … _image.htm
