[Gate-users] GATE cannot find interfile data from header

[Marc Chamberland]

That's a good point.

Hopefully, someone from the Open Gate Collaboration will fix this in v6.2.1!

Hi Marc,

Modifying the header files works, but it makes the image unreadable by other programs (e.g. xmedcon) that assume that the data is referred relatively to the header.
This should be fixed in GATE I think. No show-stopper of course.

Cheers,
Tristan

Hi Tristan!

I took a look at the source code of the Interfile reader in Gate, and yes, you do need to include the sub-directory in the Interfile header.

If you look at the Time Activity Curve example included with Gate, you'll see that they include the sub-directory in the "name of data file" in the Interfile header.

I don't know if this qualifies as a bug or not, but I'd suggest you just work around it by modifying your header files (or moving them to your execution directory).

Marc

Hi,

We have a macro involving a source in interfile format, stored in a subdirectory called "data":
[glatard at kingkong gate.sh-2294696198382639]$ grep phantom mac/adapted-mainMacro.mac  | grep -v \#
/gate/hof_brain/interfileReader/readFile data/brain_phantom.h33
/gate/source/voxel_brain/interfileReader/readFile data/brain_phantom.h33
The header of this interfile references the data relatively to the header path, i.e. without the subdirectory:
[glatard at kingkong gate.sh-2294696198382639]$ grep phantom data/brain_phantom.h33
!name of data file := brain_phantom.i33
[glatard at kingkong gate.sh-2294696198382639]$ ls data | grep phantom
brain_phantom.h33
brain_phantom.i33
GATE cannot find the data file:
[glatard at kingkong gate.sh-2294696198382639]$ ./Gate mac/adapted-mainMacro.mac 1>/dev/null
  [G4-cerr]
  [G4-cerr] Error: Could not open header file 'brain_phantom.i33'!
  [G4-cerr] ERROR - G4Box()::G4Box(): hof_brain_solid
  [G4-cerr]         Dimensions too small ! - 0, 0, 0
  [G4-cerr]
  [G4-cerr] *** G4Exception : InvalidSetup
  [G4-cerr]       issued by : G4Box::G4Box()
  [G4-cerr] Invalid dimensions. Too small.
  [G4-cerr] *** Fatal Exception *** core dump ***
  [G4-cerr]
  [G4-cerr] *** G4Exception: Aborting execution ***
Aborted
It works if we add the subdirectory to the data file name in the interfile header:
[glatard at kingkong gate.sh-2294696198382639]$ grep phantom data/brain_phantom.h33
!name of data file := data/brain_phantom.i33
[glatard at kingkong gate.sh-2294696198382639]$ ./Gate mac/adapted-mainMacro.mac 1>/dev/null
[glatard at kingkong gate.sh-2294696198382639]$ echo $?
0

Is it a bug in the interfile reader of GATE, or should we adjust interfile headers according to their location?

Thanks in advance, cheers,
Tristan
