Dear Santana, Mario

Thank you for your response!
Can I judge if the number of events is enough by the statistical error?But sometimes the statistical error in dose_50.bnn.lis is 0 while in z.dat is 45,which one should I refer to?

Best Wish!

Yes, it is the statistical error
Again, the statistical error (third column is the average, first and second the min and max of your bin)

Subject: [fluka-discuss]: Percentage error in usrbin





Dear exports'
 
I use usrbin of 2*2*5 bins to scoring dose. I ascii the usrbin result dose_50.bnn to dose_50.bnn.lis and plot the result dose_50.bnn with gnuplot in flair :z.dat(I choose z,and the limit of x,y,z is default). two questions:

1.In dose_50.bnn.lis, what dose the mean of the Percentage errors follow in a matrix A(ix,iy,iz), format (1(5x,1p,10(1x,e11.4)))

       4.6420E+00 3.5649E+00 2.8894E+00 3.1111E+00 4.7960E+00 3.3774E+00 2.5223E+00 3.1620E+00 4.6191E+00 3.1215E+00
       2.1012E+00 3.2304E+00 4.5331E+00 3.2791E+00 2.5898E+00 3.3436E+00 4.3849E+00 3.5383E+00 3.3751E+00 3.5247E+00
Is it the statistic error of 5 runs? what king of error?

2.In z.dat dose the mean of the 4th column data as follows?

     1.7919530&n! bsp;
     1.7600398
     1.6749210
     1.7426424
     1.8636131
     1.8636131

Thank you !
