Hello Hamed,
    please keep the replies within the discussion list, as the topic
might be
of interest also for others.

Regarding you questions:
1) if you are interested in numbers, you could save your results in a
formatted
    (ASCII) format to read the results directly. No plots are needed in
this case.

2) you can alse use SCORE, with all the warnings given in the manual:
SCORE and
    USRBIN per region give exactly the same output, but with score
(andEVENTDAT)
    many more information is written in the file and you might generate
very big
    data files.

Kind regards,
Andrea
