Hi Dear all,
PDFgetX2 is a GUI driven program to obtain the total-scattering
structure function S(Q) and the pair distribution function (PDF), G(r),
from X-ray powder diffraction data. Its first beta release is available at
http://www.pa.msu.edu/cmp/billinge-group/programs/PDFgetX2/
A brief user's manual is also provided with the tutorial data.In program PDFgetX2, a user-friendly GUI has been built to
facilitate user interactions with data. Standard corrections due
to background subtraction, sample absorption, polarization,
Compton intensities are available. The final S(Q) and G(r) data
files are multiple-column ASCII files with the processing parameters
in the header, which can also be saved into a history file. Reloading
of the history file will restore the full GUI section, and reproduce earlier
data analysis.
The the freely downloadable interactive data language (IDL) Virtual Machine, or the commercial (IDL) licensed distribution (version 6.0 or higher), is required for PDFgetX2 to run. Platform supported by IDL include Linux/UNIX, Windows, and MACINTOSH, and can be downloaded at http://www.rsinc.com/download/. Self-installers of PDFgetX2 are available for Linux/UNIX and Windows.
We welcome everyone to try it out, and give us feedback, comments, and bug reports.
Thank all,
Xiangyun Qiu from Billinge group at Michigan State University
