• look at the tracking efficiency with PXL, using code in CVSROOT (StiPxl)
• sample : 1 muon /event, fixed Pt and phi ~ pi (even with misaligned PXL, 1 track per event should allow the PXL hits to be taken most of the time)
• loop over global track and plot the # of PXL hits on track via 

• gTrack->fitTraits().numberOfFitPoints(kPxlId);

note :
the BFC chain has been updated friday (April 11th) with a dedicated option : StiLibsHft ; this option calls StiPxl.
I used PixelIT in this chain : PixelIT calls PxlIT which calls StiPxl, so it should be fine.

Results (over 100 events) :

Fig 1 : PXL hits from PxlHitCollection (all hits, no tracking here)
Fig 2 : TPC hits in tracking distribution : over 100 tracks, 92 are passed after cuts ; distribution looks ok
Fig 3 : PXL hits in tracking distribution : most of the tracks have 0 PXL hits, only 2 tracks have 1 PXL hit, 1 track with 2 PXL hits

Previous Simulation :
similar study with y2013 geometry and StiRnD code : here 

update :
backtracked to the version where StiVolumes are build per ladder :

1. when sensor !=1, do not build the volume
2. Set the length in Z of the Sti Volumes to 10*TGeoBBox->GetDZ()
3. Set the position in Z at 0
4. old numbering : inner ladders from 0 to 9, outer ladders from 0 to 30 
5. same numbering in StiPxlHitLoader

Test over 20 muons (17 tracks after cuts)
modif 1 : with 1) and 2)
modif 2 : with 1), 2) and 3) from the above list

# of PXL hits / track	0	1	2	3
CVSROOT	16	1	0	0
modif 1	7	5	5	0
modif 2	2	3	11	2
