Hi
I have converted your file (http://trshare.triumf.ca/~zhiyil/shld_in_sand001_fort.22) to Ascii using the flutil/usbrea utility. If I am not mistaken the file at the following location is the results of one single FLUKA run and contains the 125x250x100 value only (it would have a block with value and errors if it would be an averaged outputs).

To calculate the statistical deviation you need to run several jobs (minimum recommended is 5) with different random number seeds and average the results (straightforward with FLAIR) and the errors will be computed in this step
Regards
Joachim

Subject: [fluka-discuss]: gplevbin and errorbars

Hello,
I generated USRBIN files and use FLAIR to plots them in 1D projections. However, I checked the *.dat files generated by gplevbin, all errors are zero although I select to show error bars. No idea if the problem is from the USRBIN files or gplevin algorithm to calculate errors? My example USRBIN file (binary) is attached here:
