Hi Akio, all,

The version of the tracking code at 

https://github.com/jdbrice/star-sw-1/tree/fwd-tracking

Now writes fwd tracks into the StEvent structure as we discussed. 

You can see everything you need at this point from the `processFwdTracks` function:

void StFwdTrackMaker::ProcessFwdTracks( ){

StEvent *stEvent = static_cast<StEvent *>(GetInputDS("StEvent"));

StFwdTrackCollection * ftc = stEvent->fwdTrackCollection();

for ( auto fwdTrack : ftc->tracks() ){

auto atEPD = fwdTrack->mProjections[0];

auto atECAL = fwdTrack->mProjections[1];

auto atHCAL = fwdTrack->mProjections[2];

LOG_INFO << "Track crosses EPD @ " << TString::Format( "(%0.2f+/-%0.2f, %0.2f+/-%0.2f, %0.2f+/-%0.2f)", atEPD.XYZ.x(), atEPD.dx(), atEPD.XYZ.y(), atEPD.dy(), atEPD.XYZ.z(), atEPD.dz() ) << endm;

}

}

If you would like to use the genfit track directly then please look at the documentation that I hosted here:

https://www.star.bnl.gov/protected/lfsupc/jdb/GenFitDocs/

and specifically for the Track:

https://www.star.bnl.gov/protected/lfsupc/jdb/GenFitDocs/classgenfit_1_1_track.html

Once you have a match maker class working please feel free to push to this branch that way I can make use of it as well.

Thanks for your patience,

Daniel
