The treatment of experimental X-ray diffraction data (XRD) normally involves several steps of processing and analysis. A visual inspection of the data during the treatment is often important to follow and validate the final result. This is especially important for non-routine experiments or also when decisions on the experimental conditions should be taken on the fly e.g. in case of synchrotron beamtime limitations. In such circumstances, the availability of specific tools providing good plotting capabilities and processing options in a user-friendly environment is really helpful. The d1Dplot and d2Dplot software (for 1D and 2D-XRD, respectively) have been developed prioritizing these aspects.

D1Dplot focuses on the visualization and processing of powder diffraction data and includes the ability to generate comprehensive 2D plots of multiple patterns to easily follow e.g. solid-state chemical reactions. It also includes general tools for data processing and gives the user the possibility of creating a compound database for phase identification.

D2Dplot is a full package for 2D-XRD data [1]. It allows inspecting and interacting directly with the images. Besides general processing tools (point selection, excluded zones, background extraction, powder pattern generation, azimuthal plots) it includes specific data analysis features such as a database for the fast identification of compounds and a routine for through-the-substrate methodology [2]. The software has proved useful in the analysis of minerals [3], cultural heritage samples [4], kidney stones or crocodile teeth [5].

Both programs can be downloaded from the ALBA Synchrotron Light Source website (https://www.cells.es/en/beamlines/bl04-mspd/preparing-your-experiment) and can be used free of charge for non-commercial and academic purposes.
