Editing STIR FAQ (section)

= STIR and output of other simulators =
Note that since STIR 3.0, there is an example script to do your own analytic simulations with STIR in examples/PET_simulation.

== SimSET ==
STIR comes with utilities to read SimSET sinograms, check the SimSET subdirectory and its README.txt

== ASIM ==
See the howto on this wiki

== GATE ==
* if you have a ROOT file 
** STIR now comes with ROOT support out of the box, at least if CMake found ROOT during configuration. You need to create a small text header pointing to the ROOT file to tell STIR more about the simulation (e.g. scanner characteristics). Unfortunately, this needs to be done manually. There are 2 examples <tt>.hroot</tt> files in <tt>examples\samples</tt>. After that <tt>lm_to_projdata</tt> and any list mode reconstruction should  work.
** if you are still using STIR 3.0, try http://sourceforge.net/projects/gatepet2stir/. See also  [http://stir.sourceforge.net/MIC2013UsersMeeting/STIR_UM_2013_Efthimiou_GATE_PET_2_STIR.pdf Nikolaos' presentation at the STIR 2013 User's Meeting]
* if you output as raw, try STIR 3.0 conv_GATE_raw_ECAT_projdata_to_interfile
* if you output as ECAT7, run <tt>ifheaders_for_ecat7</tt> (you will need to have built STIR with supportfor the LLN ECAT Matrix library), and then manually edit the <tt>.hs</tt> file to reflect the correct scanner size. A lot of the info should be alright, but scanner radius and scanner name is wrong (set the latter to unknown). The radius you should know as you ran the simulation! Block info etc is currently ignored by STIR so don't bother filling it in.
* Almost working code exists to read LMF data via STIR. You can find it in the `experimental/listmode` directory. Sadly, nobody has ever finalised this.
