[Gate-users] STL file for detector

Hi everybody,
I tried to run the kidney example under:
GateContrib-master/misc/geometry_STL/kidneys and got the following error:
Core-0] Initialization of geometry
[G4-cerr] STL file corrupted: number of facets do not correspond to file
size.
^Z
[2]+ Stopped Gate mac/main.mac
I am getting the same message for the Suzanne example.
Next I tried to use STL files (binary and asci STLs attached) instead of
the "LSO" box in
GateContrib-master/imaging/PET/PET_CylindricalPET_System.mac by doing
the following editing:
# LSO layer
/gate/crystal/daughters/name LSO
#/gate/crystal/daughters/insert box
/gate/crystal/daughters/insert tessellated
/gate/LSO/placement/setTranslation -0.75 0.0 0.0 cm
/gate/LSO/geometry/setPathToSTLFile lsobox.stl
#/gate/LSO/geometry/setXLength 15 mm
#/gate/LSO/geometry/setYLength 3.0 mm
#/gate/LSO/geometry/setZLength 3.8 mm
/gate/LSO/setMaterial LSO
/gate/LSO/vis/setColor red
This example does not run anymore (it does when it uses the original
box) and I am getting:
I/O warning : failed to load external entity "./Materials.xml"
I/O warning: Discard the previous warning if your simulation doesn't
transport OPTICAL PHOTONS.
Otherwise, please copy the ./Materials.xml file from the gate-source
directory in the directory where you run your main macro.

Does anybody have a working example with STL geometry?
Thank you,
