Dear All, We are pleased to announce a new release 2.0 of the PDFgetX3 software which is now available at https://www.diffpy.org/products/pdfgetx.html. The main new features are the new program "pdfgetn3" for extracting PDFs from constant-wavelength neutron scattering data, new parameter "twothetazero" for correction of diffractometer offset, and an added support for Python 3.7 (versions 3.6, 3.5, 3.4, 2.7 are also supported). The release includes a number of fixes and improvements which are listed at https://www.diffpy.org/doc/pdfgetx/2.0.0/release.html. For more details about the new neutron PDF functionality please see recent paper in Journal of Applied Crystallography at https://doi.org/10.1107/S1600576718010002.
PDFgetX3 and PDFgetN3 are free for individuals carrying out open academic research, but require a paid license for commercial use or when multiple users will use the same copy of the software. Please contact Beth Kauderer <techtrans...@columbia.edu> if you have questions. The new PDFgetX3 and PDFgetN3 software is distributed by Columbia Technology Ventures which make it available at https://columbia.resoluteinnovation.com/technologies/M11-120.
