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.
