---++ Using Marlin Reco

We ran our own [[RunMokkaLocally][simulations locally]], using the PPE batch farm, and now we want to do reconstruction. This wiki explains how to do this, step by step.

---+++ Required processors

For full reconstruction, one needs the following processors:
<verbatim>
    <execute>
        <processor name="MyMaterialDB" />
        <processor name="MyFTDDigiProcessor" />
        <processor name="MyTPCDigiProcessor" />
        <processor name="MyVTXDigiProcessor" />
        <processor name="MySimpleCaloDigi" />
        <processor name="MyClusterCheater5_3" /> 
        <processor name="MyTrackCheaterWithFit" />
        <processor name="MyWolf" />
        <processor name="MySelectReconstructedParticle" />
        <processor name="MyLCIOOutputProcessor" />
    </execute>
</verbatim>

This list was taken from the example steering file =cheattracks+jetfind.xml= included in the !LCFIVertex package (in =ilcsoft/v01-14/LCFIVertex/v00-06-01/steering/=).

Make sure all needed processors are compiled. See [[ILCSoft#MarlinReco][this wiki]] for details on how to recompile !MarlinReco.

Make sure that the input and output collection names match between consecutive processors and also match your naming convention.

*Problems*

We noticed that the =GearOutput.xml= produced when running our [[RunMokkaLocally][simulation]] was incomplete and one would get this type of errors:
<verbatim>
 ***********************************************
 A runtime error occured - (uncaught exception):
      gear::UnknownParameterException: StripLineProperties_dEdx
 Marlin will have to be terminated, sorry.
 ***********************************************
</verbatim>
Once the missing detector parameters ([[http://llr.in2p3.fr/~ruan/PFATutorial/ReferenceFile/ILD00.gear][see this for example]]) are added though, the reconstruction runs.
