Mikhail,
I used files from your discussion with Faith:
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/7878.html
but instead of spectrum.dat I used different spectrum which I obtained by digitizing plot from this paper:
http://nopr.niscair.res.in/bitstream/123456789/14912/1/IJPAP%2050%2811%29%20818-820.pdf
(I have a fortran code that generates this data, srplot.f, but I don't know how to run it)
The only thing I changed in your source_mod.f is I set NDIMMAX=58, the number of points in my spectrum.dat
when I run it, all result points are zero. What might be the problem?
Also, it seems like I have trouble with unit conversion with the results of my previous email. According to the test-3.sum.lis, USRTRACK gives results in protons/GeV/cm^2/primary
I want result in protons/MeV/cm^2, just like in this paper (fig.5-8):
http://www.sciencedirect.com/science/article/pii/S2214552414000674/pdfft?md5=fa5b5ee5f3679917a4686acc3af31fc7&pid=1-s2.0-S2214552414000674-main.pdf
so I need to convert 1/GeV to 1/MeV and multiply it by 5e5 primaries. To do the conversion I should divide by 1000 but the fluka plot matches the plot of the source.dat only when I multiply by 1000! WTF?

Finally, what scoring cards should I use to make plots like fig.9-12 of the "Shielding evaluation..." paper? Should I create detector at each point in depth of water slab where I want the dose to be probed or I can use one detector for the hole water slab and then do a 1-D projection to get a dose profile along the slab?
thank you and sorry for the lengthy email
Roman
