Datasqueeze 2.1 is a graphical interface for analyzing data from 2D x-ray diffraction detectors (wire, image plate, CCD), running on Windows, Linux, and Macintosh OS X. The interface is simple and intuitive, and the program is easy to use even for those new to x-ray diffraction analysis. Datasqueeze is particularly useful for the analysis of powder diffraction data, diffuse scattering from polymers or liquid crystals, or small-angle scattering from colloids, polymers, gels, or solutions.

New features in Version 2.1:

• It is now possible to analyze images collected with the detector rotated far from the beam zero orientation ("Wide Angle Scattering")
• The user has substantially more control over the appearance and quality of line plots.
• The graphical indexing feature allows the user to compare the peaks in a powder diffraction pattern to selected Bravais lattices with variable lattice parameters.
• The masking option allows the user to exclude unwanted features in the data from analysis.
• The Fourier Transform feature allows the user to perform a direct Fourier Transform of the raw data.
• Instrument parameter calibration is accomplished via a user-friendly wizard.
