BacCorpus Intergenic DNA 90是一个大规模、序列级聚类的细菌基因间DNA区域数据集。它包含以90%序列一致性和90%覆盖率聚类的代表性基因间DNA序列，这些序列源自BacCorpus——一个统一处理的细菌基因组资源，涵盖数百万个质量控制的分离基因组和宏基因组组装基因组。该数据集旨在用于在细菌非编码序列上训练和评估DNA或混合模态基因组语言模型。在细菌基因组中，基因间区域可能包含启动子、终止子等调控和组织信号，以及相邻基因之间的间隔，这使得它们适用于基因组感知表示学习。数据集包括约14.5亿个代表性基因间DNA序列，格式为Parquet，主要用途是预训练细菌DNA和混合模态基因组语言模型。

BacCorpus Intergenic DNA 90 is a large-scale, sequence-level clustered dataset of bacterial intergenic DNA regions. It contains representative intergenic DNA sequences clustered at 90% sequence identity and 90% coverage, derived from BacCorpus, a uniformly processed bacterial genome resource spanning millions of quality-controlled isolate genomes and metagenome-assembled genomes. This dataset is intended for training and evaluating DNA or mixed-modality genomic language models on bacterial non-coding sequence. In bacterial genomes, intergenic regions can contain regulatory and organisational signals such as promoters, terminators, and spacing between neighbouring genes, making them useful for genome-aware representation learning. The dataset includes approximately 1.45B representative intergenic DNA sequences in Parquet format, primarily for pretraining bacterial DNA and mixed-modality genomic language models.
