Why Datasqueeze?Modern x-ray diffraction (XRD) is very often performed using two-dimensional, or "area" detectors--the solid state equivalent of film. Commonly used technologies include CCD detectors (usually with some kind of x-ray fluorescent screen), other solid state technologies, image plates, or wire detectors. These are generally supplied by the vendor with built-in software that collects the data and performs some kind of specialized analysis, such as protein crystallography or phase identification via powder diffraction.The problem comes when the user tries to use the equipment for a purpose other than that envisioned by the manufacturer--for example, looking at small-angle x-ray scattering (SAXS) from protein solutions, or diffuse scattering from amorphous polymers, on a system intended for crystallography. The scientist then quickly encounters two related problems: the on-board software is not sufficiently flexible to perform the desired analysis, and the file format structure is so obscure that what started as a simple data analysis project turns into a lengthy exercise in interpreting binary data with custom compression. This is where Datasqueeze comes in. This application allows you to read most of the XRD formats that are currently on the market (with more being added continuously), analyze the data, and export the results on both graphical and text formats that can be easily used by other applications. |
Datasqueeze will run on multiple platforms, including Windows, Linux, and Macintosh OS X. This means that the scientist is not tied to the computer that produced the data, or to a central "analysis computer," but can carry the data off to his or her office to be examined at leisure.
Datasqueeze is particularly useful for the analysis of powder diffraction data, diffuse scattering from polymers or liquid crystals, or small-angle scattering ("SAXS") from colloids, polymers, gels, or solutions.
