Geant4
GATE V8.0: current GATE release from 04/2017
Recommended configuration
Geant4: v8.0 validated for Geant (remains backward compatible with Geant !! but no longer supported !!)
Compiler: gcc 4.8 to 6.2
ROOT: last versions of ROOT 5 and ROOT 6
ITK: version 4.9 or later
CLHEP: version embedded from Geant4 available since GATE V Users can also use the external CLHEP version recommended by Geant4 ( )

3. No really new features and/or developments
Next GATE release: V8.1
No really new features and/or developments
but rather bug fixes
Most of these bugs (and their fix) are referenced in GitHub
Issues: any GitHub user can create an issue
Pull requests: any GitHub user can propose some code changes to fix a bug

4. GATE on GitHub: issues https://github.com/OpenGATE/Gate/issues/
To create a new issue

5. GATE on GitHub: pull requests
To open a new pull request

6. Add GATE-RTion project with TPSPencilBeam source validation procedure
GateContrib
Since GATE V8.0, all examples have been definitely removed from the Gate source code repository
Now available on a new user-oriented repository named GateContrib
Open and publicly available on GitHub as part of the OpenGATE collaboration organization
!! NEW !!
Add GATE-RTion project with TPSPencilBeam source validation procedure

7. Git extension for versioning large files
GateContrib
When you create a pull request so as to provide an example that test your new feature, don’t forget to use Git LFS if it contains associated data
Git extension for versioning large files
How to ????
Everything is mentioned in details in readme.md file
.pdf
.raw
.root
.i33
.bin
.mha
.png
.tar.gz
.docx
.stl
.gnumeric
Current list of tracked patterns (file types) identified by us as binary that must be managed with Git LFS
Which files ?
$ git lfs track

8. New rules regarding GATE releases
Systematically plan 2 releases per year
Even if there is no really new features to advertise to users
Because bug corrections are always welcomed !
Fix the release date and strictly respect it
1st of October
1st of March  GATE release validated with the last Geant4 version (usually released early December)
To be discussed in SC

9. Traditional benchmark tests
Five historical benchmarks are included in each GATE distribution
Systematically run (by Seb, David and I) before each new release to verify the integrity of the source code
Each benchmark consists of:
Set of macros required to run the simulation
ROOT code to analyze the simulation output and generate figures
Set of baseline figures to compare results with those from a correct run RT
PET
SPECT
/benchmarks/benchRT
/benchmarks/benchPET
/benchmarks/benchSPECT
ROOT analysis with BenchAnalyse.C (in /output)
ROOT analysis with benchmarkPET.C
ROOT analysis with benchSPECT.C

10. New benchmarking system
A new benchmarking system has been included since V8.0
To quickly validate installation (
To ensure easy and regular checks of the source code integrity
It provides
3 tests dedicated to radiation therapy applications
benchRT_gamma
benchRT_proton
benchRT_carbon
4 tests dedicated to imaging applications
benchImaging_optical
benchImaging_ct
benchImaging_spect
benchImaging_pet
Same as traditional benchRT
All benchmark tests can be easily run with make test

11. How to use GATE benchmarking system ?
It requires a specific CMake configuration
To enable benchmarking system
(Required if GATE_USE_ECAT7 is set to ON)
To get reference results (stored on Midas)
If let to OFF (default), benchImaging_pet
and benchImaging_optical tests will not be performed

12. How to use GATE benchmarking system ?
After make and make install, type make test
$ make test
Running tests...

1. Execute Gate macros
2. Perform some comparisons based on
List of specific files to be compared
Some diff commands: diff, diff_stat, diff_dose
3. Return result (success/failure)
At the end of make test process, you should see

13. Logo contest
Just as Geant4 did last year, we could set an open competition for the creation of a new GATE logo
The competition could be open until spring 2018 so that the final decision could be made during the next steering committee
Use the GATE website or create a specific one See
