Introduction

The GSAS-II environment contains the full GSAS-II graphical suite pre-installed on an Ubuntu desktop. Use it to:

• Import and visualise X-ray or neutron powder / single-crystal diffraction patterns
• Perform Rietveld refinement, Pawley fits, PDF analysis, texture, size–strain and more
• Plot difference curves, reciprocal-space maps and peak statistics.
