Dear Fluka experts and users,
I am trying to use the meshtk utility to add up usrbin files.
I have two usrbin files as follows:
each usrbin has three scoring sections (ambient dose) for neutron , photon and total .
I issued the command to sum two usrbins as follows (according to the meshtk manual):
meshtk 1.11e+05 10X0_21.bnn:1-3 + 1.18e+05 2X0_21.bnn:1-3 -o sum.bnn
the sum.bnn is the summation of two usrbins and is generated in the same working directory.
However, when I try to plot sum.bnn I see the following error in Flair saying the usrbin is not valid:
Am I missing something in this process?
I appreciate any comments.

Dear @vasilis
Thanks for your reply.
I sent the bnn files via email as they are quite big size files to be uploaded here.
Thank you.

Thank @mahdi for the files.
it helped to find a formatting error in meshtk.
The corrected version of the program you can find in the flair download page as beta version 3.x-5
cheers

Thank you @vasilis ,
Now it’s working.
May I ask how the errors of the summation are treated? Are they sum in quadrature?
I tried to plot the 2D error distribution using the sum.bnn , but the plot was empty. Do I need to run another command to get the overall statistical error?
Thanks,
Mahdi

Normally yes, however if you don’t get the statistical error, then something is wrong I will check and let you know
