Hi Joachim,
On the output terminal I did not find the command lines about how
gplevbin is used to generate 1D or 2D projection data files. I am using
the latest version of FLUKA (32bit) and FLAIR. Could you give an example
how to use the command "gplevbin" in a terminal? Sometime it is handy to
write a script to generate a lot of plots.
Thanks,
Zhiyi.
