Server Menu

The NXRefine plugin to NeXpy installs a top-level menu labelled “Server”, which is used to launch and monitor data reduction operations performed as part of the workflow.

Manage Workflows

This dialog initializes a new experiment directory layout using the server settings to initialize default locations. When the dialog is launched, click on “Choose Experiment Directory” to launch the system file browser in order to select or create the new experiment directory.

Copy Parameters

This dialog creates NeXus files that are used as templates for the experimental files that are used to store all the data and metadata associated with a particular set of rotation scans. The initial metadata is defined by parameters in the settings file in the tasks sub-directory, which can be modified by the “Edit Settings” sub-menu described below. However, some of the metadata will be refined using a powder calibration, whose results are then stored in this file.

Manage Server

This dialog will import a TIFF or CBF file containing measurements of a powder calibrant and refine the detector position and coordinates, using the PyFAI API. Alternatively, if the calibration parameters are already available in a PONI file, they can be directly imported. The resulting powder data and calbration parameters are then saved to the configuration template previously created using the New Configuration dialog.
