Unfortunately after updating both:

fts.geo ( geometry directory)

PndFtsMapCreator ( fts directory)

The issue with the tube mapping mentioned previously still
exists.
For my part, i solved the problem for the FTS digitizer by taking the tube
geometrical information directly from the TGeoManager nodes and i am
storing the tube geometry directly in the PndFtsHit structure ( for now )

When i run the FTS digitizer using both the new tube mapping ( with the updated
fts.geo ) i am getting now a systematic X coordinate mismatch i.e :
In the text dump that follows, one has to compare geometrical information

- from the MC points ( Geant point )
- from the mapper ( Tube from mapper )
- from the TGeoManager directly ( Tgeo Tube position ) :
