Hi, The idea of the the applications like rtkfdk.cxx is to use gengetopt, a command line parser, to pass options. See for example https://wiki.openrtk.org/index.php/RTK/Scripts/FDK What is actually done for the projections reader is here https://github.com/SimonRit/RTK/blob/master/include/rtkGgoFunctions.h#L176-L270 but you don't have to use ggo, you can do it your own way.
