Abstract This application will provide urgently needed analytical methods to develop the field of imaging genetics. SOLAR-Eclipse is an integrated suite of resources for genetic and epigenetic analyses such as heritability, pleiotropy, high-resolution genome-wide association (GWA) and Whole-Genome Analyses (WGA), gene expression, quantitative trait loci-linkage (QTL-L) and methylation analyses optimized for traits derived from structural and functional neuroimaging data. Our focus is on phase 3 development to support full-resolution voxel-and-vertex-wise analyses of imaging genetics networks involved in complex polygenic illnesses. During the first two funding periods, we demonstrated the utility of SOLAR-Eclipse for imaging genetics applications and developed strong “Pull/Push” collaboration with three major NIH brain imaging initiatives: the NIH Big Data 2 Knowledge (BD2K) Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA), Human Connectome Project (HCP), MRI-GENIE, CHARGE and UK Bio Bank. During these funding periods, we released over 20 software updates and this support was acknowledged in ~250 manuscripts. We focused the next phase of SE development on the needs identified by our Big Data partners. The first aim is to revise our software to support “Repeat, Rerun, Replicate (R3)” initiative, including Python based application programming interface for straightforward integration of SOLAR-Eclipse into modern processing workflows. It will include a new data format optimized for voxel-and-vertex wise imaging genetic analyses including GWA and WGA, as well as recording the provenance of imaging genetics data analysis workflows. Aim 2 is focused on enabling GWA and WGA at full voxel-vertex-and- genetic resolution. This will derive and perform causality testing and annotation for the imaging-genetic networks while accounting for linkage disequilibrium (LD) and spatial dependency patterns and correcting for multiple comparisons. We will perform causative inference testing for the vertical and horizontal pleiotropies - the two main mechanisms that govern genetic risk factors for complex polygenic illnesses such as schizophrenia. Aim 3, we will execute collaborative studies to tune novel methods in large and diverse samples assembled by our Big Data partners: ENIGMA, HCP, SiGN, UKBB and others. This collaborative piloting and honing of novel methods will serve to popularize and disseminate our developments for individual imaging genetics labs.

摘要 这一应用将提供急需的分析方法，以发展成像遗传学领域。 SOLAR-Eclipse是一套集成的遗传和表观遗传分析资源，如遗传力， 多效性、高分辨率全基因组关联（GWA）和全基因组分析（WGA）、基因 表达，数量性状基因座连锁（QTL-L）和甲基化分析优化的性状来自 结构和功能神经成像数据。我们的重点是第3阶段的开发，以支持全分辨率 复杂多基因疾病中涉及的成像遗传学网络的体素和顶点分析。期间 在前两个资助期，我们展示了SOLAR-Eclipse在成像遗传学应用中的实用性 并与三个主要的NIH脑成像计划开展了强有力的“拉/推”合作：NIH大数据 2知识（BD 2K）通过荟萃分析（ENIGMA）增强神经影像学遗传学，人类 Connectome Project（HCP）、MRI-GENIE、CHARGE和UK Bio Bank。在此期间，我们 发布了20多个软件更新，这种支持在大约250篇手稿中得到了认可。我们把重点放在 根据我们的大数据合作伙伴确定的需求进行下一阶段的SE开发。第一个目标是修改我们的 支持“重复、重新运行、复制（R3）”计划的软件，包括基于Python的应用程序编程 界面，可直接将SOLAR-Eclipse集成到现代处理工作流程中。它将包括一个 新的数据格式优化体素和顶点成像遗传分析，包括GWA和WGA， 以及记录成像遗传学数据分析工作流程的起源。目标2的重点是使 GWA和WGA在全体素顶点和遗传分辨率。这将推导并执行因果关系测试， 注释的成像遗传网络，同时考虑连锁不平衡（LD）和空间 依赖模式和校正多重比较。我们将进行因果推理测试， 垂直和水平的多效性-两个主要机制，管理遗传风险因素的复杂 多基因疾病，如精神分裂症。目标3，我们将进行合作研究，以调整新的方法 我们的大数据合作伙伴收集了大量不同的样本：ENIGMA，HCP，SiGN，UKBB等。 这种新方法的合作试点和磨练将有助于推广和传播我们的 为个人成像遗传学实验室的发展。
