Latest revision as of 11:41, 25 October 2024

Overview

As of early 2017, for new work, it is recommended to use the NXcanSAS (multi-dimensional) standard for both 1-D and n-D data to maximize the chance that other software will be able to read your data files.

We strongly encourage all authors of small-angle scattering related software to add support for NXcanSAS.

Latest News

Steve King: 2024-09 : Proposals for NXcanSAS 1.1 in development

Paul Butler: 2019-07 : Lots of discussion at canSAS-XI about metadata. Discussion and actions from the meeting are available canSAS-XI/DataFormats

Examples and Usage

The following are example v1.1 compliant 1D data files containing [besides essential metadata] - right-click & save as to view, stylesheet is on the TRAC site:

SANS data only ISIS_SASXML_v1_1_SANS_Example.XML
Wavelength-dependent transmission ISIS_SASXML_v1_1_Transmission_Example.XML
Wavelength-dependent monitor spectrum ISIS_SASXML_v1_1_Monitor_Spectrum_Example.XML
Wavelength-dependent detector efficiency ratio ISIS_SASXML_v1_1_Det_Efficency_Example.XML

The files can be usefully displayed in many web browsers: Rendering_canSAS1D_in_Web_Browsers
