DESCRIPTION (provided by applicant): Project Summary/Abstract Mega2, the Manipulation Environment for Genetic Analysis, is a unique open-source computer program for facilitating the creation of analysis-ready datasets from data gathered as part of a genetic study. Mega2 transparently allows users to process genetic data for family-based or case/control studies accurately and efficiently. In addition to data validation checks, Mega2 provides analysis setup capabilities for a broad choice of commonly-used genetic analysis programs. It has served an important role in the genetics research community worldwide. Under this proposal, we plan to enhance the capabilities of Mega2, while applying best practices in software engineering to meet these critical needs of an open-source project: portability across OS platforms, ability to evolve with the needs of genetics research, extensive documentation, maximizing code reuse, as well as systematic testing, debugging and maintenance. Specifically, we plan to make Mega2 much easier to extend, repair, and maintain by streamlining it and restructuring it as an object-oriented application, implementing an application programming interface and a graphical user interface, and creating a dynamic mechanism for adding new input formats, filters, and output formats. We plan to improve Mega2's large-scale data handling in order to meet the needs of the research community by adding a fast interactive mode, implementing adjustment layers for modifying and filtering original data, and supporting an intermediate pre- validated data format. We plan to extend Mega2's interoperability by supporting more input formats and analysis programs, improving connections to existing databases, and integrating Mega2 within the Galaxy workflow pipeline. We plan to continue to maintain Mega2 as a public resource, constantly revising it to support the very latest versions of the supported analysis programs, carrying out rigorous and extensive quality-control testing, and maintaining and improving the documentation. Accomplishment of these aims will significantly improve Mega2's usability, data input handling capabilities, abilities to set up target analyses, extensibility, maintainability, and interoperability, thus ensuring continuing usefulness and availability of this widely-used software. Mega2 has been used to accelerate gene discovery studies for a large list of complex human diseases. Improving this crucial resource will have a significant impact on speeding up the gene-discovery process, which in turn will ease the healthcare burden due to complex genetic disease in the US and world-wide.

Mega2，遗传分析的操作环境，是一个独特的开源计算机程序，用于促进从作为遗传研究的一部分收集的数据创建分析就绪数据集。Mega2透明地允许用户准确有效地处理基于家庭或病例/对照研究的遗传数据。除了数据验证检查外，Mega2还为广泛选择的常用遗传分析程序提供了分析设置功能。它在全球遗传学研究界发挥了重要作用。根据该提案，我们计划增强Mega2的功能，同时应用软件工程中的最佳实践来满足开源项目的这些关键需求：跨操作系统平台的可移植性、随着遗传学研究的需要而发展的能力、广泛的文档、最大化的代码重用以及系统的测试、调试和维护。具体来说，我们计划使Mega2更容易扩展、修复和维护，方法是将其精简并重组为一个面向对象的应用程序，实现一个应用程序编程接口和一个图形用户界面，并创建一个动态机制来添加新的输入格式、过滤器和输出格式。我们计划通过增加快速交互模式、实现用于修改和过滤原始数据的调整层以及支持中间预验证数据格式来改进Mega2的大规模数据处理，以满足研究界的需求。我们计划通过支持更多的输入格式和分析程序、改进与现有数据库的连接以及将Mega2集成到Galaxy工作流管道中来扩展Mega2的互操作性。我们计划继续将Mega2作为公共资源进行维护，不断修改它以支持最新版本的支持分析程序，执行严格而广泛的质量控制测试，并维护和改进文档。这些目标的实现将显著提高Mega2的可用性、数据输入处理能力、建立目标分析的能力、可扩展性、可维护性和互操作性，从而确保这个广泛使用的软件的持续有用性和可用性。Mega2已被用于加速一系列复杂人类疾病的基因发现研究。改善这一关键资源将对加速基因发现过程产生重大影响，从而减轻美国和世界范围内复杂遗传疾病造成的医疗负担。
