Run FOQUS

The specific command to launch FOQUS depends on the operating system.

To launch FOQUS, open the Anaconda prompt (or appropriate terminal or shell depending on operating system and choice of Python), and run the following commands:

conda activate ccsi-foqus
foqus

Alternatively on Windows you can start FOQUS by double-clicking on the “ccsi-foqus” Desktop shortcut created when FOQUS was first installed. That shortcut can be recreated at any time by opening a terminal, as described above, and starting FOQUS with the “make shortcut” option:

foqus --make-shortcut

Note

The first time FOQUS is run, it will ask for a working directory location. This is the location FOQUS will put any working files. This setting can be changed later.

Note

Files passed as command line arguments to FOQUS will be relative to where FOQUS is run. Once FOQUS starts, file paths will be relative to the FOQUS working directory.

Note

If when running on a remote Linux server or Virtual Machine you encounter an error when starting FOQUS similar to:

PyQt5 or Qt not available

or:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Try installing the libgl1-mesa-glx and/or libxkbcommon-x11-0 packages using the package manager appropriate for your Linux distrubution. (i.e. apt-get install on Ubuntu).
