摘要

ESRF 升级计划的第二阶段不仅提供了一个新的存储环(极亮源,EBS),还对几条光束线进行了翻新。BioSAXS 光束线(位于 BM29 端口)进行了升级,配备了一个新的摇摆源和一个更大的探测器。所有分析软件都已重写,以应对增加的数据通量,并继续实时为光束线用户提供经过缩减和预处理的数据。本文介绍了FreeSAS和Dahu(用于将数据分析与光束线控制连接起来的工具),FreeSAS是各种小角散射分析算法的开源集合,可用于还原和分析BioSAXS数据。它进一步介绍了光束线不同数据采集模式的数据处理管道,这些模式可以使用样品更换器采集单个均质样品,也可以使用在线尺寸排阻色谱设置。

New data analysis for BioSAXS at the ESRF.

The second phase of the ESRF upgrade program did not only provide a new storage ring (Extremely Brilliant Source, EBS) but also allowed several beamlines to be refurbished. The BioSAXS beamline (located on port BM29) was upgraded with a new wiggler source and a larger detector. All analysis software has been rewritten to cope with the increased data flux and continues to provide beamline users with reduced and pre-processed data in real time. This article describes FreeSAS, an open-source collection of various small-angle scattering analysis algorithms needed to reduce and analyze BioSAXS data, and Dahu, the tool used to interface data analysis with beamline control. It further presents the data-processing pipelines for the different data acquisitions modes of the beamline, using either a sample changer for individual homogeneous samples or an inline size-exclusion chromatography setup.
