EXALT (EXpression signature AnaLysis Tool) is a computational system enabling comparisons of microarray data across experimental platforms and different laboratories http://seq.mc.vanderbilt.edu/exalt/. An essential feature of EXALT is a database holding thousands of gene expression signatures extracted from the Gene Expression Omnibus, and encoded in a searchable format. This novel approach to performing global comparisons of shared microarray data may have enormous value when coupled directly with a shared data repository.
EXALT（表达特征分析工具）是一个计算系统，可实现跨实验平台和不同实验室的微阵列数据比较（http://seq.mc.vanderbilt.edu/exalt/）。EXALT的一个基本特征是一个数据库，其中包含从基因表达综合数据库中提取的数千个基因表达特征，并以可搜索的格式进行编码。当直接与共享数据存储库结合使用时，这种对共享微阵列数据进行全局比较的新方法可能具有巨大价值。
