-====== Electron ion collier studies ======+[[community:hepsim:|<< back to HepSim manual]]
  
-This wiki explains how to view electron-proton collision events. The analysis package is described in +====== EIC software and detector studies ======
-[[https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=fcs:fpad| FpadSoft]]+
  
  
-We will use e-p events shown in [[http://atlaswww.hep.anl.gov/hepsim/index.php?c=emp&e=141&t=all]]. +  * **[[fcs:eic:intro| Introduction to EIC examples]]**
-The full simulations are located under the tag "rfull001", which corresponds to SiD simulations. +
- +
-====== Visualizing events with Jas ====== +
- +
- +
-You can run Jas3 to visualize the simulated events.  Install Jas3 as: +
-<code bash> +
-wget http://java.freehep.org/maven2/org/freehep/jas-assembly/3.1.3/jas-assembly-3.1.3-distribution.tar.gz -O - | tar -xz; +
-cd jas-assembly-3.1.3/ +
-./jas3 +
-</code> +
-For windows:  use the [[http://jas.freehep.org/jas3/Download.html|Jas download page]] and then run it using "jas3.bat". +
-Then install the needed plugins **[View]-[Plugin manager]** and install HEP packages "visualization"- +
-"Wired4", and "org.lcsim". Restart Jas3. +
- +
-Then copy the detector geometry file to the local directory where the file "jas" is: +
-<code bash> +
-wget http://atlaswww.hep.anl.gov/asc/hepsim/soft/detectors/sidloi3_heprep.tgz -O - | tar -xz; +
-</code> +
-This will create a directory "detector". This detector corresponds to "rfull001" tag used for the reconstruction of events +
-in [[http://atlaswww.hep.anl.gov/hepsim/index.php?c=emp&e=141&t=all]]. +
- +
-Now we can visualize the detector as **[File]-[Open data source]-[HepRep]** XML and select file "detector/sidloi3/sidloi3.heprep". +
-This is how to do this using the command line: +
- +
-<code bash> +
-./jas3 detector/sidloi3/sidloi3.heprep +
-</code> +
-Now you should see the detector layout. +
- +
-Next, we will read the simulated events: Open any *.slcio file you copied from HepSim using the menu +
-**[File]-[Open data source]-[LCIO]** +
-For e-p events, use this LCIO file from [[http://atlaswww.hep.anl.gov/hepsim/show.php?item=159&reco=rfull001|rfull001]]. +
- +
-<code bash> +
-wget http://mc.hep.anl.gov/asc/hepsim/events/ep/141gev/lepto6ard_dis5q2//rfull001/lepto6ard_dis5q2_0001_pandora.slcio +
-</code> +
- +
- +
- +
- Then click a small button [Go] (top menu bar). It will process +
- events.  Then select again **[File]-[New]-[Wired 4 view]**. If you want to see how data records are organized inside the slcio file, +
-do this **[File]-[New]-[LCSim Event browser]** +
- +

-====== Now to analyse full simulations  ====== +
- +
- +
-Please read  [[https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=fcs:fpad| FpadSoft]] +
