9. Run OpenTOPAS on LANTA
...
Two approaches for running OpenTOPAS on LANTA are presented below.
...
.
A. Batch job
This first approach, using a job script and sbatch command, is recommended. For performance reasons, every graphic option, Gr/*/, should be disabled, please visit https://opentopas.readthedocs.io/en/latest/parameters/graphics.html for complete details.
...
(Also see https://thaisc.atlassian.net/wiki/spaces/LANTA/pages/447021064/Quick+Start+Guide#6.-Running-your-job)
B. Interactive session
This second approach can be useful. However, this method is not recommended if your internet connection is poor or you have to run topas for a long time.
You can directly access LANTA computing nodes by requesting request an interactive session . For by executing, for example, execute

sinteract -p compute -c 16 -t 06:00:00 |
(You could add -X option to enable X11 forwarding for OpenGL/graphic features. Please visit Interactive session and https://opentopas.readthedocs.io/en/latest/parameters/graphics.html before using this capability.)
After the requested resources are allocated, you can use this session to run topas and interactively execute commands afterwards. For example,

topas $HOME/Applications/TOPAS/OpenTOPAS-install/examples/Basic/TwoBeams.txt |
