====== process_2pass.pl ====== The primary processing script is called ''process_2pass.pl''. It will run a long series of scripts that will eventually produce a differential interferogram. The script requires only the name of the parameter file as an argument: $ process_2pass.pl param.txt Processing a single interferogram takes on the order of half an hour to an hour. All output files and directories will be placed in the directory where ''param.txt'' resides. If the script terminates successfully, the final line of terminal output will be "That's all folks." For details about how to start and stop the script at various points, see [[:roipac:process:process2pass_details|process_2pass Details]].
