This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Recent acquisition and adoption of a Rayonix MX225-HE detector requires additional features from the MarParse program, which was initially developed to analyze the isotropic scattering data acquired by the MarCCD165 detector. MarParse is used to convert the 2D raw images obtained from the CCD detectors into a universal data format expressed in I(Q) vs Q through several steps of numerical data processing, including statistical evaluation and background subtraction. Enhancements include 1) the removal of zingers in the raw images, this is important to take the advantage of the high sensitivity of the MX225-HE detector and allows images to be acquired in normal mode, saving beam time; 2) choice of image shape, this is to be used to identify whether the image is rectangular (acquired by the MX225-HE detector) or circular (acquired by the MarCCD165 detector); and 3) ability to handle images of large sizes, up to 4096x4096 pixels. MarParseDlg, a GUI-based MarParse program, has been developed to improve the user experience. MarParseDlg reads a parameter file and runs data processing. Besides the capabilities of MarParse, it can be used to periodically look up a directory for a new data set and run quick analysis as soon as the data have been saved in the directory, and plot the fully processed data in the form of I(Q) vs Q. A new installer program, MarParseSetup, has also been developed to install MarParse on a PC smoothly, solving the potential problem of running MarParse on a PC that does not have the latest Mircosoft dynamic link libraries. The rapid data processing capability of MarParse and MarParseDlg has contributed to highly effective data collection, especially in time-resolved studies, by allowing the user to plan the next experimental conditions carefully in a much more timely fashion. The software has been made available on the web, and there has been 57 downloads of MarParse by scientists from 25 institutions in 8 countries since August 1, 2007, when the recording of downloads was started.

该副本是利用众多研究子项目之一 由NIH/NCRR资助的中心赠款提供的资源。子弹和 调查员（PI）可能已经从其他NIH来源获得了主要资金， 因此可以在其他清晰的条目中代表。列出的机构是 对于中心，这不一定是调查员的机构。 最近的收购和采用roonix MX225-HE检测器需要Marparse计划的其他功能，Marparse计划最初开发出来分析MARCCD165检测器获得的各向同性散射数据。 MARPARSE用于通过数值数据处理的几个步骤，包括统计评估和背景减法，将从CCD检测器获得的2D原始图像转换为在I（Q）与Q中表达的通用数据格式。 增强功能包括1）在原始图像中删除Zingers，这对于利用MX225-HE检测器的高灵敏度并允许在正常模式下获取图像并节省光束时间很重要； 2）选择图像形状，这是用于确定图像是矩形（由MX225-HE检测器获取）还是圆形（由MARCCD165检测器获取）； 3）能够处理大小的图像，最高4096x4096像素。 Marparsedlg是一项基于GUI的Marparse计划，已开发出来改善用户体验。 marparsedlg读取一个参数文件并运行数据处理。 Besides the capabilities of MarParse, it can be used to periodically look up a directory for a new data set and run quick analysis as soon as the data have been saved in the directory, and plot the fully processed data in the form of I(Q) vs Q. A new installer program, MarParseSetup, has also been developed to install MarParse on a PC smoothly, solving the potential problem of running MarParse on a PC that does not have the latest Mircosoft dynamic链接库。 MARPARSE和MARPARSEDLG的快速数据处理能力通过允许用户以更及时的方式仔细计划下一个实验条件，从而有助于高效的数据收集，尤其是在时间分辨研究中。该软件已在网络上提供，自2007年8月1日开始下载记录以来，来自8个国家的25个机构的科学家下载了57个Marparse。
