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

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

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

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:

export PATH=/cvmfs/ilc.desy.de/sw/x86_64_gcc44_sl6/CED/v01-09-02/bin/:$PATH

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:

unset LIBGL_ALWAYS_INDIRECT

Running digitization and reconstruction

Use the latest SiDReconstruction.xml attached to this twiki page. You also need to have the basic gear_sid.xml file in your directory. For example (assuming you are in the lcgeo directory):

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

Once you've done this, and assuming you are still in the lcgeo directory, and you have initialised your session as above, run

Marlin SiDReconstruction_v03_160711.xml
and this will produce a file named sitracks.slcio located in the current directory.
