pygdatax 0.2.12

Python libray for Small Angle Neutron (SANS) and X-ray (SAXS) scattering data treatment and visualization.

PYGDATAX

Python libray for Small Angle Neutron (SANS) and X-ray (SAXS) scattering data treatment and visualization. This package can be used for the following instruments :

• Xeuss 2.0 SAXS instrument
• SANS_LLB instrument installed at the Paul Scherrer Institut (PSI)
• Xeuss 2.0 in reflectivity mode

Installation

To install pygdatax, run:

pip install pygdatax

Depending on your OS and python distribution, you may need to install PyQt5 and Ipython

pip install pyqt5 Ipython

Upgrade Version

pygdatax package is up to now often upgraded. In order to get the last version type the following command in your terminal or acaconda prompt

pip install --upgrade pygdatax

Launch Graphical User Interface for Xeuss data treatment and visualization

To launch the GUI, run in you terminal (or conda prompt):

pygdatax_gui

This GUI can also be used to visualize nexus files from SANS_LLB.

Run Graphical User Interface for scan log file visualization

From version 0.1.8, a new application is available allowing to preview and fit the scan logfile of the Xeuss spectrometer

To launch it , run in your terminal the command:

pygdatax_log

The two curves plotted per scans corresponds to the roi0 (integration over the instrument's roi) signal and ct0 signal (full detector sum)

To fit one curve, you can use the fit widget present within the toolbar. The fit will be performed on the current plot window which means that one can fit a speific part of the curve by zooming on it.

Run Gaphical User Interface for X-Ray reflectivity treatment and visualzation

from version 2.0.0, a new application allows to treat and vizualize X ray reflectiviy measurements performed on the Xeuss 2.0 apparatus. The command to run it is:

pygdatax_rx
