[Gate-users] projection images

[Rajaram, Ramya (H USA)]

Thank you MJ - I was able to use Matlab to read in the .sin file but see only zeros and ones in it. Why is that? I am using the benchSPECT macro (gate.sin)
Another question: I have root output enabled - I can see the different graphs that the Hits and Singles trees generate but is there a way to arrive at the numbers behind the graphs? For instance, how do we know the position (energy, time, etc) of a certain event at the detector? Is that a fair bit of C++ or other programming, or does root offer ways to do it?
Thank you all for your help and time,
Ramya

Dear Ramya,

I usually use "matlab" and "C++" for the post-processing.

If you want to only display, you can use bunch of programs, such as 'mricro'.

Cordially yours,
MJ
