The TIMEleSS viewer is a simple application to view series of 3D-XRD data files. It is built on top of silx which was developed at ESRF to provide a collection of Python packages to support the development of data assessment, reduction and analysis applications at synchrotron radiation facilities. silx aims to provide reading/writing tools for different file formats, data reduction routines and a set of Qt widgets to browse and visualise data.

Multigrain diffraction features are all accessible from the 3D-XRD extra menu and include

• plotting series of EDF files with omega values
• overlay peaks from a peak search
• subtract a background (from a median image, for instance)
• Play with image orientation and the flip matrix (O-matrix) options
• Stack all images
• Save a mean or median image for background evaluation
