Once you have compiled Legolas it will have placed an executable in your current working directory (or in the source directory if you chose an in-repository build). The executable can be run in two ways, either through direct calling or through the Pylbo interface.
1. Running Legolas directly
Passing parameters to Legolas is done through the use of a parameter file.
If you’ve set up your current running directory using
setuplegolas.py, the script will have asked to copy over the
parfile. Edit this file to your needs, take a look at the different possibilities.
Afterwards you simply call the executable from the command line, passing the parfile as an option:
./legolas -i parfile.par
The output is one single file, placed by default in a subdirectory
output which is created during compilation.
2. Interfacing with Pylbo
A second way to run Legolas is through the Pylbo-interface, which is extremely handy when you are doing parametric studies or want to run multiple setups at once. This obviously requires you to have Pylbo installed, explained here. More information on how to run Legolas like this can be found on the Interfacing with Legolas page.
