Pydidas quick-start guide

Pydidas is usable both through its graphical user interface as well as through the command line / notebooks.

To quickly start using pydidas, there are multiple options:

• Entry points (if pydidas was installed using pip)

• Scripts in the pydidas_scripts folder.

• Using the pydidas module in the python shell.

Entry points

If installed as wheel, pydidas offers the following entry points:

• pydidas-gui to start the graphical user interface.

• pydidas-documentation to open the pydidas documentation in the default system web browser. Note: The pydidas module must have been run at least once (either through opening the GUI or imported in a python shell) for the documentation to have been created.

• pydidas-clear-settings Remove the stored registry keys for pydidas.

• pydidas-updater Start a script which automatically updates pydidas to the latest version available on GitHub.

• pydidas-remove-local-files This script removes all local log files and stored configuration files.

• run-pydidas-workflow Script to run a defined workflow in the console. This script also requires configuration files for the scan and diffraction experiment. Please refer to the full documentation for more details.

• remove-pydidas Remove all local config files and registry settings from the system. Please note that this script will not remove the python code itself, but only cleans up the system.

Scripts

Pydidas includes multiple scripts which are located in the pydidas_scripts folder, which is located in the same folder as pydidas. These can be called directly by python from the command line and they are:

• pydidas_gui.py to start the GUI.

• pydidas_documentation.py to open the html documentation in a browser.

• run_pydidas_workflow.py to run a processing workflow on the command line.

• pydidas_updater_script.py to update pydidas to the latest release published on GitHub.

• clear_local_settings.py to remove all registry settings written by pydidas.

Example

If pydidas, was installed in /user/myname/code/python/my_packages/pydidas, the pydidas_scripts will be located in

$ cd /user/myname/code/python/my_packages/pydidas_scripts
$ python pydidas_gui.py

Command line

Much of pydidas’ functionality is also available from the command line or notebooks. Pydidas can be imported and used as any other python module. Please refer to the documentation, in particular to the Command line manuals.
