| Larch: Data Analysis Tools for X-ray Spectroscopy

# 4.2. GSECARS Mapviewr

The main Larch GUI gives a simple view of a Larch session.

The GSECARS Mapviewer is a main GUI for Larch, allowing users to read and display HDF5 files containing X-ray fluorescence maps from synchrotron X-ray microprobes. In the main frame (left), the user can select what map files and what portions of the data set to view. On the right, is one of the views of XRF map, shown in a false-color image (using using wxmplot and matplotlib). Images are interactive, allowing zooming, changing color thresholds, and drawing lasso boxes to extract full X-ray fluorescence spectra, show below.

The X-ray fluorescence spectra extracted from a XRF Map.

Other displays of the same XRF Map data. On the left, 3 different elements are encoded into Red, Green, and Blue. On the right, an interactive display of the correlation of two maps is shown.

Larch can also handle micro-X-ray Diffraction maps, with a simple view of a diffraction pattern shown here.
