IGUAPE - Paineira Graphical User Interface for Kinetic Experiments#
This is the documentation web page for IGUAPE, the Paineira Graphical User Interface for Kinetic Experiments. The software was developed to provide a friendly and easy way for PAINEIRA (PNR) users to visualize and make qualitative data treatment of Powder X-ray Diffraction (PXRD) data acquired during in situ experiments.n During this type of experiments, hundreds of PXRD data are generated. Visualization and data treatment are not straight forward with such a volume of data. IGUAPE provides a Graphical User Interface (GUI), associated with a python backend, that can read the large volume of data produced at PNR. The software was developed to read data acquired at Paineira, and does not support data from other sources. However, it is possible to change the Monitor class, found in the soruce code, to support other data sources.
In this web page you’ll find the documentation for IGUAPE’s source code and a brief tutorial showcasing the software’s capabilities.

abstract = {Synchrotron radiation X-ray diffraction facilities equipped with fast area detectors can generate X-ray diffraction (XRD) patterns in seconds. This capability is fundamental to revealing transient crystalline phases and the structural evolution of samples and devices for technology applications. However, it generates XRD patterns usually faster than the user can process during the experiment. Thus, an open-source and user-friendly software package named {\it IGUAPE} was developed for the PAINEIRA beamline (Sirius, Brazil). It allows visualization of the X-ray diffractograms as soon as the azimuthal integration of the Debye rings is processed and the XRD pattern is created. The software can also perform a single-peak qualitative analysis of the diffraction data. Upon selecting a diffraction peak in the XRD pattern, the peak position, integrated area and full width at half-maximum variation during the {\it in situ} or {\it operando} experiment are given.},
