Re: [fluka-discuss]: How to export 3D data in txt/dat format in fluka/flair

Dear Giulia,

- How should I use/call the "usrbrea.f" file to get formatted data file?
My input file is produced by process in Flair.

- I tested saving the E data in ASCII format! In the resulted
FileName00#_fort.98 I got the (ten column) matrix of the data. But I
don't know how to:

1- associate each data value with its corresponding x,y,z (voxel)
coordinate value!

2- Differentiate data from error (or the errors are not included here?)

Best regards,

Tamer
