medarc/gtex-10M-balanced-tiles
收藏资源简介:
该数据集包含1000万个JPEG编码的224x224病理切片,来自GTEx SVS幻灯片,平衡分布在40个组织前缀上,每个前缀250,000个切片。源对象小于80,000,000字节的已被忽略,因为GTEx前缀包含不支持的小型SVS对象。切片从虚拟OpenSlide级别0、1和2中采样,因此有效视野变化,而输出的JPEG大小保持固定。每个parquet行包含与nanopath风格切片加载兼容的path和jpeg列,以及tissue、slide_id、subject_id、x、y、level、source_px、downsample、s3_uri和tissue_fraction元数据。
This dataset contains 10,000,000 JPEG-encoded 224x224 pathology tiles from GTEx SVS slides in `s3://path-datasets/gtex/svs_by_tissue`, balanced at 250,000 tiles for each of the 40 tissue prefixes. Source objects under 80,000,000 bytes are ignored because the GTEx prefix contains tiny unsupported SVS objects. Tiles are sampled from virtual OpenSlide levels 0, 1, and 2, so the effective field of view varies while the emitted JPEG size stays fixed. Each parquet row has `path` and `jpeg` columns compatible with nanopath-style tile loading, plus `tissue`, `slide_id`, `subject_id`, `x`, `y`, `level`, `source_px`, `downsample`, `s3_uri`, and `tissue_fraction` metadata.
