VisualizationGeant4 : Visualization of Configuration has some mistakes When I use the model of [VisualizationGeant4]

1

For some reason, I cannot get the visualization on my institute cluster having access to CVMFS. Here is what I am doing:

source /cvmfs/clicdp.cern.ch/software/allpix-squared/1.6.1/x86_64-centos7-gcc10-opt/setup.sh

I have used the following configuration files as an example:

Main config

[Allpix]
detectors_file = “tutorial-geometry.conf”
log_level = “WARNING”
number_of_events = 1

[GeometryBuilderGeant4]

[DepositionGeant4]
particle_type = “Pi+”
source_energy = 120GeV
source_type = “beam”
beam_size = 3mm
source_position = 0um 0um -200mm
beam_direction = 0 0 1
physics_list = FTFP_BERT_EMZ

[ElectricFieldReader]
model=“linear”
bias_voltage=-50V
depletion_voltage=-30V
output_plots = 1

[ProjectionPropagation]
temperature = 293K
output_plots = 1

[SimpleTransfer]
output_plots = 1

[DefaultDigitizer]
output_plots = 1

[VisualizationGeant4]
mode = “gui”
driver = “OGL”

Geometry

[detector1]
type = “timepix”
position = 0mm 0mm 0mm
orientation = 0deg 0deg 0deg

This is the log of running:

allpix -c tutorial-simulation.conf

But I have no way of visualizing it smoothly.
The error as follow:

Hi @Newyean

it seems like not all GLX/Xrandr/X libraries are supplied by the LCG view on CVMFS, but for some it seems to rely on the system-installed ones - which seem to be missing in your case. I cannot find a list of locally required libraries, but likely the CERN SFT/LCG people can help you here.

Have you by any chance tried using a more recent version of Allpix Squared and see if the issue also persists there?

Cheers,
Simon

Thanks for your reply!
I do this is through the computer cluster, and then use a more recent version
/cvmfs/clicdp.cern.ch/software/allpix-squared/latest/x86_64-centos7-clang12-opt/
by:

Is there any way you can install xcb-utils on your cluster computer? This seems to be necessary to run Qt. If not, then unfortunately the visualization won’t work there, but the rest of the framework should not be affected by this.

Cheers,
Simon

Thank you for your advice, it seems that I can‘t achieve visualization.

Hi Newyean,

I have the same problem with visualization. I tried different ways but it didn’t work. @simonspa i am receiving the same following message …
qt.qpa.plugin: Could not find the Qt platform plugin “xcb” in “”
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem… it is still not working because we have xcb-utils on our cluster computer. However i have an ad-hoc solution for this problem, i don’t know why is it working. whenever i need to check visualization, i use the following source command.
source /cvmfs/clicdp.cern.ch/software/allpix-squared/2.0.0/x86_64-centos7-gcc10-opt/setup.sh.
It perfectly works for visualization, and for other stuff i go back to latest.
@Newyean do you have any update about the problem you were facing ?

Unfortunately, I don’t have any update or effective solutions to this problem.

Hi @sakzai

if v2.0.0 works then it is likely an issue with Geant4 which has been updated to v11 since the release of Allpix Squared 2.0. Could you cross-check that things are working with Version 2.3.3 (still on Geant4 10.7 with LCG101) but not anymore with v2.4.0 (on Geant4 11.0.2 with LCG102)?

Cheers,
Simon

Hi @simonspa thank you for comment and guidance. Fortunately, it is also working with Version 2.3.3. It doesn’t work when i mention latest or 2.4.0 in the source command

Hi @sakzai

thanks for checking, then it indeed seems to be related to the Geant4 version we are using. I will follow this up for the next release.

Best,
Simon

I tried the solution mentioned above but it didn’t work, here is what it gives:

Fatal in TROOT::InitInterpreter: cannot load library /cvmfs/sft.cern.ch/lcg/views/LCG_99/x86_64-centos7-gcc10-opt/lib/libRIO.so: undefined symbol: _ZN7TThread3RunEPv

I am using Allpix Squared version v2.0.0-1567-g217bdd4b5-dirty

Please if you can help me with this, since I tried to install allpix on my PC but I got many errors, so both ways are not working for me.

Best regards,

Hasan

Hi @hdarwish

It looks like you are attempting to run a CentOS7-compiled Allpix Squared on a Red Hat Enterprise Linux 9 machine (as all default LXPLUS nodes are). Please see our latest release notes and use an appropriate version.

Best,
Simon

Dear @simonspa,

Thanks a lot for your reply.
Finally, it works now.

Best regards,
