Access rights of sigmapi.bin file included in the tar distribution have been checked and modified according to your recommendation.
No other installation problem. Ran files are now generated nicely and simulation can be performed.
The last respin will be updated by our system supervisor (Yannick).
Thanks for quick assistance. Regards,

sigmapi.bin is a data file included in the fluka distribution. It is
opened, read, and closed by the code during initialization. In your case,
the code cannot open it.

You can check that it exists in $FLUPRO, if not someting went wrong with
the installation, please install again.( And I would advise you to update
in any case to the last respin fluka2020.0.3 )

Since your installation is in a system area, check also that the file
protections allow you to read it.

.. hope this helps
