Metadata are what makes databases searchable. Without them, researchers would have difficulty finding data with features they are interested in. Brain imaging genetics is at the intersection of two disciplines, each with dedicated dictionaries and ontologies facilitating data search and analysis. Here, we present the genetics Brain Imaging Data Structure extension, consisting of metadata files for human brain imaging data to which they are linked, and describe succinctly the genomic and transcriptomic data associated with them, which may be in different databases. This extension will facilitate identifying micro-scale molecular features that are linked to macro-scale imaging repositories, facilitating data aggregation across studies.

遗传学-BIDS 扩展：简化与人脑成像相关的遗传数据搜索

元数据使数据库可搜索。没有它们，研究人员将很难找到具有他们感兴趣的特征的数据。脑成像遗传学处于两个学科的交叉点，每个学科都有专门的词典和本体来促进数据搜索和分析。在这里，我们介绍了遗传学脑成像数据结构扩展，由与它们相关联的人脑成像数据的元数据文件组成，并简要描述了与它们相关的基因组和转录组数据，这些数据可能位于不同的数据库中。此扩展将有助于识别与宏观成像存储库相关联的微观分子特征，促进跨研究的数据聚合。
