[Gate-users] GATE ECAT7 Help

[Bohnenberger, Hendrik]

Hello Jonathan

I had a similar problem with the ECAT output in vGate. You can solve this problem as follows. 
First download the 'GATE 5.0.0 Installation Guide for Ubuntu' from the GATE homepage under Documentation --> Installing Gate. Included in this file you find the ECAT libraries with a custom ECAT makefile. Copy the Ecat libraries in your gate folder. In the makefile you have to change "CC=cc" to "CC=gcc" (1st line). Then just do make and make install. After that you have to set the environment variables. Just type 'export ECAT7_HOME=path/of/the/ECAT_libraries' into the env_gate.sh file. Source this file and recompile gate itself. 
Hope it helps

Kind regards

Hendrik Bohnenberger

Hello,
I am using vGATE and I am having trouble running the example_PET problem
with the ECAT7 output. I get the following error message:

I have followed the instructions of two different sites:
 http://cc.in2p3.fr/docenligne/674/en#0.7
And
The manual:
Installation

In order to compile the ecat7 output module of Gate, the ecat library
written at the PET Unit of the Catholic University of Louvain-la-Neuve (UCL,
Belgium) is required. It can be downloaded from their web site:
http://www.topo.ucl.ac.be/ecat_Clib.html

Three files are required: the library file libecat.a and the two header
files matrix.h and machine_indep.h.

To compile Gate with the ecat7 library without changing the env_gate.csh and
GNUmakefile files, the en- vironment variable ECAT7_HOME has to be defined
and set to the name of the home directory where the ecat7 library is
installed (for example, /usr/local/ecat7). In this ecat7 home directory, two
subdirectories should be created: lib and include. The header files are put
in the ${ECAT7_HOME}/include directory. For each system, a specific
subdirectory named after the G4SYSTEM environment variable value should be
created in the ${ECAT7_HOME}/lib directory. The corresponding library file
libecat.a has to be located in this ${ECAT7_HOME}/lib/${G4SYSTEM} directory.
The matrix.h file has to be modified to add the declaration of the
mh_update() function. The following line can be added in the "high level
user functions" part of matrix.h:

int mh_update(MatrixFile*);



I have also tried export G4ANALYSIS_USE_ECAT7=1.
Please any suggestions would help, thank you.

Jonathan Madsen
