  You don't really need to use these two binaries in your case. You can 
just use /castor-GATERootToCastor/ (see below)

- /castor-PetScannerLutEx/ is just an example code to help generating a 
LUT for castor for a specific system. The geometrical characteristics of 
the new system must be implemented directly in the code. For GATE you 
have more automatic tools.

- /castor-GATEMacToGeom/ does generate the castor geometry file (.geom) 
for your GATE simulation, but you can do it directly with 
/castor-GATERootToCastor/ as described below.

You should add the /-geo/ option to your command-line which will 
automatically generate the geometry file in the scanner repository 
(basically doing the same as castor-GATEMacToGeom). You should not 
provide the path to your system file to the /-s /option, but the alias 
of the system (the file name). It will look for this file in the scanner 
repository (config/scanner). So you can either:

- Just use "/-s my_scan/" in your command-line, it will look for a file 
called "/my_scan.geom/" or "/my_scan.hscan/" in the scanner repository. 
In your case, you already have an /out.geom/ file corresponding to your 
geometry, so you can use "/-s out/"

- (recommended) Add /-geo / to your command-line, it will generate the 
geometry file using the name provided with the /-s /option.


Cheers,

Thibaut
