[Gate-users] voxelized phantom and GATE

[Shahla Razaghi]

Dear Gate users;

I want to use Zubal voxelized phantom in my simulation. I have
downloaded Zubal phantom data and converted it to uint16 using the
following simple commands in MATLAB:

clear
clc
fid=fopen('voxel_man.dat','r');
a=fread(fid,'int8');
a=reshape(a,[128 128 243]);
b=uint16(a);
fid1=fopen('zubal.dat','w');
fwrite(fid1,b,'uint16');
fclose(fid1);
fclose(fid);

After that I converted the Zubal data format to interfile using
(X)Medcon. Every thing seems to be correct but after running my macro
with GATE6.2 the following messages appear and running procedure
aborts.

'nrecognised type name 'unsigned integer
 Header read from       'zubal1.h33'

I do not know the reason of the problem and what to do to solve it.
I do appreciate any suggestion.
