- Download Red2D.zip and unzip the file.
- Put the Red2D folder in /Documents/WaveMetrics/Igor Pro User Files/Igor Procedures.
- Restart Igor Pro.
Red2D is a small data reduction package to convert 2D elastic scattering patterns to 1D I-q profile, working on a scientific data analysis software Igor Pro. This package handles data reduction for small/wide-angle X-ray scattering (SAXS/WAXS), small-angle neutron scattering (SANS), and static light scattering (SLS). This package is easy to install (See Installation) and contains basic reduction features, suitable for light users. For more comprehensive data reduction and analysis, I recommend using Irena/Nika/Indra developed by Dr. Jan Ilavsky.
- Load 2D scattering patterns (32bit signed integer tiff)
- Display 2D images and 1D I-q or I-2θ profiles
- Get beam center and SDD by fitting standard samples (AgBh, Si, CeO2, Chicken Tendon)
- Make and apply masks on images
- Perform circular average or sector average with solid angle correction.
- Normalize 1D I-q profiles with exposure time, transmittance, sample thickness, absolute intensity correction, and support cell and solvent subtraction.
- Batch reduction of multiple images
- Support tilted detector
- Fit standard samples even when the beam center is outside the image
- ROI mask and sector mask are available
- Azimuthal angle vs q profiles
- Combining multiple images into one image
- Igor Pro 9.1 or later (Igor Pro 9.0 contains a bug that prevents this package from working correctly.)
- This package has been tested on macOS and Windows.
- This package does not support Igor 8 or older.
- Please refer to the manual, included in the Red2D.zip, for a step-by-step introduction.
Thank Dr. S. Nakagawa for helping me add the tilted detector correction and check the validity of reduced 1D profiles.
