If you plan to analyze your data using Excel, you may want to generate the output files with the headers. Once you have generated the output, you will first need to extract the output files. Then open Excel, select Open from the File menu, and browse to the location of the output file you wish to open. Change the “All Excel Files” option to “All Files” in the drop down menu above the Open button, then select the file you want to open. A Text Import Wizard in Excel will pop up and should already recognize that the .txt files are tab delimited. Select “finish” to open the file.
