I have put the nx, ny, nz ,dx ,dy ,dz on the first line, then put the pixel numbers. I write a C program to do this, i use "\n" to separate each number, and the number is store as a unsigned integer(2 bytes).But when i put this phantom.dat in the mac file, it requests me to make a table.dat to be the translator.Can you help me for giving an example for this table.dat, how can i make the materials to relate with the pixel numbers? Thanks, i am look forward to your reply.       yours, Sheng ye   2007.2.13   2007/2/13, Richard Taschereau <RTaschereau@mednet.ucla.edu>: <BLOCKQUOTE>The "parameterizedBoxMatrix" is not available with Gate 1.0.2.   Richard On 2/9/07 10:44 PM, "sheng ye" <beyond071@gmail.com  <mailto:beyond071@gmail.com> > wrote: <BLOCKQUOTE>Hi all,              I got a problem while making a voxellized phantom. It could  be found in chapter 7 of Users Guide, which  about how to write a voxellized  phantom. It says that parameterized volume method is now available in GATE for voxellized phantoms. And it gives the  keyword "parameterizedBoxMatrix" in the insert command:                                        /gate/world/daughters/name anyname /gate/world/daughters/insert parameterizedBoxMatrix.       I followed the guide,but error occurs during GATE running.The error is "parameter value is not  listed in  the candidate list", now i  don't know how to deal with it.
