2. Status
FEDRA installed on ccali and integrated with OpRelease as an external kit (in the same way as root), so all it’s libraries and functions becomes accessible from the code or from scripts.
The interface classes of OpEmuRec to FEDRA algorithms of “linking”, “alignment”, “tracking”, “vertexing” are implemented.
The access for reading/writing of data from/to trees of OpRData is implemented
FEDRA package used with EmuRec is identical to the standalone version. The additional classes are added as a part of the OpEmuRec package

6. FedraEmrIO class
void SegmentEmr2Edb( REMULRawData &sr, EdbSegP &sf ); EdbSegP *SegmentEmr2Edb( REMULRawData &sr); void SegmentEdb2Emr( EdbSegP &s, REMULRawData &sr ); REMULRawData *SegmentEdb2Emr( EdbSegP &s ); EdbTrackP *TrackEmr2Edb( REMULTrack &trE ); void TrackEmr2Edb( REMULTrack &trE, EdbTrackP &t ); REMULTrack *TrackEdb2Emr( EdbTrackP &t ); void TrackEdb2Emr( EdbTrackP &t, REMULTrack &trE ); int VertexEdb2Emr( EdbVertex &v, REMULVertex &vE ); Bool_t LayerEdb2Emr( EdbScanSet &sc, int iplate, int side, REMULLayerAlignment &la ); void LayerEdb2Emr( EdbLayer &l, REMULLayerAlignment &la ); void WriteAlignment( EdbScanSet &sc ); void WriteVolume( EdbPVRec &ali ); void ReadVolume( EdbPVRec &ali );

7. Example of using IO
EdbPVRec *ali=0; // void vol_tr() { TFile* f = TFile::Open("opemurec.root"); TTree* treeTK = (TTree*)(gROOT->FindObject("TreeTK")); FedraEmrIO feio; fieo.eTKTreeManager = EmulTKTreeManager::giveThis(treeTK,"read"); ali = new EdbPVRec(); feio.ReadVolume(*ali); ali->Print(); }

8. Conclusion and outlook
Technical problems are solved and basic volume reconstruction is possible
All Fedra functions (including displays, MCS momentum estimation, etc) can be called on the EmuRec data by the user scripts
Interfaces debugging and in some cases completion is required (experienced Fedra users can easily contribute to this job)
Many upgrades and modifications will be necessary for the full event analysis when the DataMap structure will be ready
