---+ Getting Started with Reconstruction for  SiD(Sillicon Detector)   Tracking system

<br />Tracking system in SiD(Sillicon Detector) represented by such components: Main Tracker(all sillicon ), Vertex Detector, Forward Tracker.

---+++ Important version notes

We are running on SL6 machines and haven't tried other architectures. Note that you must have =cvmfs= installed (ask your local sysadmin).
Latest update was on 5 Sept 16, using the latest ilcsoft release *v01-17-10* for everything.


---+++ Running  simulation

Assuming you are in the =lcgeo= directory (else do =cd ../=), and that you have *initialised your session as above*, do
<verbatim>
python example/lcio_particle_gun.py
ddsim --compactFile=SiD/compact/SiD_o2_v01/SiD_o2_v01.xml --runType=batch --inputFile mcparticles.slcio -N=1 --outputFile=testSiD_o1_v03.slcio
</verbatim>

---+++ Visualizing the output using CED

Note that for the event display to work I had to ask my local sysadmin to install *freeglut* (e.g. for SLC6, =freeglut-2.6.0-1.el6.x86_64=) so that the library =libglut.so= was available. Point to a CED installation with glced:
<verbatim>
export PATH=/cvmfs/ilc.desy.de/sw/x86_64_gcc44_sl6/CED/v01-09-02/bin/:$PATH
</verbatim>

A few extra parameters are missing from the =SiD_o1_v03.xml= in =v01-17-10=, so download and put the modified =SiD_o1_v03a.xml= attached to this page in your local =lcgeo/SiD/compact/SiD_o1_v01/= directory.
You may need to make the following environment modification, depending on your local machine and how you connect to it:
<verbatim>
unset LIBGL_ALWAYS_INDIRECT
</verbatim>
Below you can see visualization of ttbar event:

---+++ Running digitization and reconstruction

Use the latest [[%PUBURLPATH%/%WEB%/%TOPIC%/SiDReconstruction_v03_160711.xml][SiDReconstruction.xml]] attached to this twiki page. You also need to have the basic [[%PUBURLPATH%/%WEB%/%TOPIC%/gear_sid.xml][gear_sid.xml]] file in your directory. For example (assuming you are in the =lcgeo= directory):
<verbatim>
wget https://twiki.ppe.gla.ac.uk/pub/LinearCollider/GlaSiDGettingStarted/SiDReconstruction_v03_160711.xml
wget https://twiki.ppe.gla.ac.uk/pub/LinearCollider/GlaSiDGettingStarted/gear_sid.xml
</verbatim>

Once you've done this, and assuming you are still in the =lcgeo= directory, and you have *initialised your session as above*, run
<verbatim>
Marlin SiDReconstruction_v03_160711.xml
</verbatim>
and this will produce a file named =sitracks.slcio= located in the current directory.
