Hi!

The genfit demo is running now with geane! Several things have been fixed, so that it is also possible now to read back Tracks with a GeaneTrackRep into ROOT.

If you check out revision 2436 the relevant changes in trackrep/ genfit/ and recotasks/ should be available. The demo should run out of the box:

> root -l -q recotasks/demo/runMC.C
> root -l -q recotasks/demo/runDemo.C
> root -l -q recotasks/demo/plotDemo.C

this will run the fit with the LSLTrackRep.

To change to GEANE look into runDemo.C and activate Geane:

  DemoDemoPatternRecoTask* DemoPR = new DemoPatternRecoTask();
  DemoPR->AddHitBranch(2,"PndTpcPoint");
  //  DemoPR->AddHitBranch(3,"MVDPoint");
  DemoPR->SetPersistence();
  //DemoPR->UseGeane();      // uncomment this line!
  fRun->AddTask(DemoPR);

In the plotDemo.C macro it is also shown how you can access fit information from the ROOT command line, with a simple draw command.

Unfortunately not everything is going correctly. Here are the resulting plots (Tracks of 500MeV, Theta=40deg):

For LSLTrackRep:
index.php?t=getfile&id=4334&private=0

For GeaneTrackRep:
index.php?t=getfile&id=4335&private=0

I will look into that... Maybe someone could try the macro, if the behaviour can be reproduced..?

Cheers! Sebastian.
