Dear Castor users and developers,
I'm trying to reconstruct the data coming from a scanner I simulated
with gate (MyScanner.mac).
When I use the castor-GATEMacToGeom the conversion goes fine but I
think there is something strange in the converted .geom file
(Myscanner.geom):
1) The .geom file generated by the utility contains the following lines
layers size depth : 12
layers size transaxial : 1.6
layers size axial : 1.6
I think that they should be like this:
crystals size depth : 12
crystals size trans : 1.6
crystals size axial : 1.6
2) In the .mac file I provided you, the original rsector offset is 61.4
mm from the center of the FOV.
/gate/rsector/placement/setTranslation 61.4 mm
In the .geom file the scanner radius is reported as
scanner radius : 61.4
However, If I understood correctly, the scanner radius should be
61.4- crystals size depth/2.0.
3) I noticed that the utility doesn't support the /control/alias
statement of GATE is there any plan to implement it?
4) Minor thing:
When I run the GATERootToCastor utily
./castor-GATERootToCastor -i ~/prova_nick/PointSource_X0_Y0_Z0.root -m
~/MyScanner/MyScanner/example_castor.mac -o ./test-output -s MyScanner
I got this error

***** GetGATESystemType() -> Error : Couldn't open mac file
/home/nick/MyScanner/MyScanner//home/nick/MyScanner/MyScanner/MyScanner/MyScanner_geometry_castor.mac
!
***** castor-GATERootToCastor :: GATE system type not found :
This script only supports conversion for cylindricalPET and ecat systems
The system type is recovered from the lines '/gate/systems/...'
***** Exit function called. Abort with code 1.
I think that this is due to the path of the file
~/MyScanner/MyScanner/example_castor.mac begin process in a wrong way.
Thank you for your support and best regards
