Data Reduction, Visualization and Analysis
Getting your data
Raw data from non-proprietary experiments is available in our data repository at http://dx.doi.org/10.18434/T4201B (also available by ftp:// at the same location), as specified in our Data Management Plan.
Available software
There are a number of software packages available to NCNR users. Some must be used locally at the NCNR and others may be downloaded and used at your home institution. This page is a list of the available programs organized by topic. Those programs that can be downloaded are indicated with a D in parentheses (D) but most of these programs can be run locally on JAZZ. The platforms supported for the downloadable programs are indicated within the web pages.
CRYSTALLOGRAPHY
The following software were originally developed by Brian Toby while a staff member at the NCNR. They are currently being maintained at ANL, with links provided here for your convenience.
- EXPGUI/GSAS Reduction and analysis of data for x-ray and neutron diffraction measurements: BT-1
- CMPR Display, index and fit diffraction data
- other crystallography resources
REFLECTIVITY
Reduction, visualization and analysis of data from the PBR, MAGIK, and NG-7 reflectometers (with future support for CANDOR). Support for the reflectivity programs: paul.kienzle [at] nist.gov (Paul Kienzle)
- Reductus online data reduction
- Refl1D (D) advanced fitting with Python
- Unpolarized neutron reflectivity (web calculator)
- Polarized neutron reflectivity (web calculator)
- Full details of reflectometry software
INELASTIC NEUTRON SCATTERING
- DAVE (D)
For reduction, visualization and analysis of data from DCS, FCS, HFBS, SPINS, FANS (BT-4), BT2, BT7 and BT9.
Support for DAVE: richard.azuah [at] nist.gov (Richard Azuah) - XTREAT, TANQENS
For reduction and analysis of data from FCS
Support for XTREAT and TANQENS: taner [at] nist.gov (Taner Yildirim) and craig.brown [at] nist.gov (Craig Brown) - FIT (only inside firewall) (D)
For fitting generic columnar-formatted datasets.
Support for FIT: ross.erwin [at] nist.gov (Ross Erwin)
SANS
Support for SANS software: jkrzywon [at] nist.gov (Jeff Krzywon)
- IGOR* programs (D)
For reduction and visualization of data from USANS, NG-B 30m SANS, NG-B 10m and NG-7 SANS - SasView (D)
For analysis of data from USANS, NG-B 30m SANS, NG-B 10m and NG-7 SANS
Online calculators
In addition to the resources above, there are a number web-accessible tools for experimental planning and simulation:
- Neutron attenuation and activation (BT-1)
- X-ray absorption calculator (anl.gov)
- VSANS Online Calculator (only inside firewall)
DVA Team
The DVA team is responsible for meeting the visualization and analysis software needs of the NCNR scientific staff and user community. There are a number of software packages listed above that are relatively mature and some that are in the development phase. The two major efforts currently in the development phase are the DAVE project and reflectivity software development.
