<HTML> <HEAD> <TITLE>Re: [Gate-users] CompressedMatrix phantom object</TITLE> </HEAD> <BODY> Hi Hyejoo, Unfortunately, the answer is no; there is no “include” list that would work the opposite way than the “include” list does.  You will have to list all organs.

On p 89 of the latest user guide manual, it says that I could exclude regions from being compressed by listing the materials. Is there any way to list a whole phantom (patient) in the exclude list other than listing all the organs?  What I am thinking to do is to compress all the voxels of the air around the phantom but not the phantom itself.
