QGSaveInputFile is an option for
QGCreateAmp, which specifies where to save the QGRAF input
file "qgraf.dat". This file is automatically created from
the input parameters of QGCreateAmp but it must be located
in the same directory as the QGRAF binary when QGRAF is invoked. The
default value is False, which means that "qgraf.dat" will
be deleted after the successful QGRAF run. When set to
True, "qgraf.dat" will be copied to the
current directory.
Specifying an explicit path will make QGCreateAmp put
"qgraf.dat" there. Notice that only the file for generating
the amplitudes is saved. The file for generating the diagrams (if
exists) is identical except for the difference in the style line.
