[Gate-users] phase space

[David Boersma]

Dear M Shahrivar,

It depends a bit on which format you chose for storing the phase space.

If you used ROOT, then you could have a look at one of the 
PhS-Analysis.C ROOT macros. For release 8.0 and newer you'll find it in 
the "GateContrib" examples as

dosimetry/Radiotherapy/example4/PhS-Analysis.C

and for release 7.2 and older (when examples were still included in the 
source code) you can find it under

examples/example_Radiotherapy/example4/PhS-Analysis.C

Check for "Ekine" and histoEnergy.

ASIDE: If you are not yet familiar with ROOT then you may want to spend 
some time with a good ROOT tutorial, in particular to learn about its 
concept of a "ROOT tree" and about the "ROOT histogram"; in particular 
how to loop over a tree and "fill" histograms. For first explorations 
you can also check out the "TBrowser" and the "ROOT tree viewer". Be 
warned that ROOT is a very big library/framework/spaceship full of very 
diverse and complicated particle physics data analysis tools, it's easy 
to get overwhelmed and lose focus on what you actually need from it. 
You'll need to find a smart balance between goal orientedness and 
attention to detail... :-)

If you are are already familiar with some other analysis software 
(matlab, python/scipy, ...) then I'd advise to import the phase space 
into that software and save time by not having to learn ROOT. (Maybe we 
should include some python-based analysis examples in GateContrib...)

HTH,
David B.
