[Gate-users] Problems with voxelized_phantom_source file

[Ana Margarida Mota]

Dear Gate users,

I am having some problems with GATE7. I am new at Gate so I apologize if
the questions I ask here are basic. I have mainly 3 questions:

(1) In examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source/ why the
data file brain_phantom.i33 is brain_phantom.md5?What is the meaning of md5?

(2) In the same folder, when I try to run mainMacro.mac, it starts normally
but than suddenly stops and I receive the message
"*GateVImageVolume.cc (l.570):  I find R=25907 in the image, while range
stop at 15*"
What's wrong?

(3) I try to run the same file but with my voxelized source and I receive
the following error:



















*GateSourceVoxelImageReader::ReadFile : fileName: ', assuming default
BIGENDIAN'LITTLEENDIAN'nrecognised type name 'unsigned integer', assuming
default BIGENDIAN'BIGENDIAN'nrecognised type name 'unsigned integer Header

and after some lines:


**** Break *** segmentation violation*



My interfile is:

Can anyone help me please??

Thank you!!
