Issues

The following issues needing infrastruture work were identified at the workshop:

Reconstruction

PFA "template" into which different (clustering etc) algorithms can be inserted
Complete finding/fitting package
Ability to reconstruct event particle by particle
Cluster finding should be steered on physics quantities (interaction lengths, etc)
Track seeded cluster finding.

Some outstanding issues which need discussion
- Add CellID to TrackerHit
- Entry/Exit point for SimTrackerHit

Need example of how to add new items to WIRED
- Need tutorial documentation on HepRep capabilities
Need more advanced examples

Drivers etc
- Should be possible to add a subdriver without causing to be explicitly called.
- Driver should provide standard way to control input/output collections
- Logging, should be improved.
  - Improve filter example
Steering file for offline use (adopt Marlin scheme?)
Ability to save MCParticle with cheater clusters
Ability to sort on columns in LCIO Event Browser
Event Overlays
Hit neighbour calculation in corners, detector overlap regions
Improve sampling fraction handling in calorimeter
Ability to integrate Marlin/lcsim processors.
DigiSim should produce SimCalorimeterHits?

Should add support for flags (EM,HAD,Digital,Analog etc) for sub-detectors.
Access to properies of materials. Calculation of dE/dx.
- Maybe should add dE/dx calculation to materials subsystem
More realistic LDC geometry description (octagonal calorimeter)
