USER ORIENTATION, TRAINING AND SUPPORT FOR BIO-SAXS/D DATA ACQUISITION AND DATA

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 SSRL SMB中心的工作人员为每个用户组提供有关SMB SAXS/D仪器有效使用的实践培训。 所有用户首先会收到针对BL 4 -2的简要安全性说明和仪器概述，包括最近设备变更的更新。工作人员讨论用户的实验要求，必要时配置仪器并培训用户。用户会收到一份关于Blu-Ice软件的教程，该软件用于BL 4 -2上的所有类型的实验，特别强调特定的数据收集？标签？数据收集所需的软件，例如用于溶液散射研究的solSAXS选项卡。他们还接受了样品处理设备的指导和SAStool的教程，这是SMB员工开发的用于非结晶衍射研究的数据处理程序。向用户提供了数据分析初始步骤的指导，例如检查数据是否可能出现辐射引起的聚集现象和评估数据质量。工作人员还可以帮助用户制定数据收集战略。由EMBL-Hamburg小组开发的数据处理程序Primus用于数据显示和计算基本结构参数，如回转半径（Rg）。BTP工作人员通过测量第一组X射线散射数据，引导用户完成上述所有操作。工作人员还应要求提供关于Fit 2D的简短教程，Fit 2D是在欧洲同步辐射设施开发的。这些实践培训课程面向新用户和有经验的用户群体。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The SSRL SMB Center staff provides each user group hands-on training on the effective use of the SMB SAXS/D instrument. All users first receive a brief safety orientation specific to BL4-2 and an overview of the instrument, including updates on recent equipment changes. The staff discuss user experimental requirements, configure the instrument as necessary and train users. Users receive a tutorial on Blu-Ice software used for all types of experiment on BL4-2 with particular emphasis on a specific data collection ?tab? required for their data collection, for instance the solSAXS tab for solution scattering studies. They also receive instruction on sample-handling equipment and a tutorial on SAStool, the data processing program for non-crystallined diffraction studies developed by the SMB staff. Users are instructed on initial steps of data analysis, such as inspecting data for possible radiation-induced aggregation and assessing data quality. The staff is also available to help users set up data collection strategies. The data processing program Primus, developed by an EMBL-Hamburg group, is used for data display and computing basic structural parameters such as radii of gyration (Rg). The BTP staff walks users through all the above by measuring first set of x-ray scattering data together. The staff also gives a short tutorial on Fit2D, developed at the European Synchrotron Radiation Facility, upon request. These hands-on training sessions are given to new as well as experienced user groups.
