收藏资源简介:
ECLIPSE public 4D-STEM 是一个公开的4D扫描透射电子显微镜(4D-STEM)数据集集合。它汇集了来自其他研究组已发表的实验4D-STEM数据,并以统一的、无损压缩的HDF5格式(扩展名为.e4d)重新托管,且带有完整且经过验证的校准元数据。该数据集旨在为各种剂量范围内的重建、压缩和去噪方法提供基准测试平台,涵盖叠层衍射(ptychography)和纳米束衍射(nanobeam diffraction)两种模态。每个文件均保证无损性(原始数据与声明变换后的立方体完全一致)、校准完整性(能量、汇聚半角、扫描步长、探测器采样、扫描-探测器旋转、离焦量等参数均标明来源并经校验)以及剂量信息(标明是电子计数、原始探测器单位还是预处理值)。数据集中包含一个固定的基准感兴趣区域(benchmark_roi),便于进行可比较的基准测试。目录表列出了19个数据集,涉及多个材料体系(如STO、NNO、La3Ni2O7、PdCuSi、polySi、PdH、SiGe、NVdiamond、AlAu、UCNP、SAEP、PBTTT、AlSPED、MOF、apoF、MAPbI3、MoS2MoSe2、Sb2S3),剂量范围从约6 e/Ų到5.7e6 e/Ų,探测器包括Merlin Medipix3RX、EMPAD、Gatan K3、Dectris ELA、4D Camera、MerlinEM、Gatan CCD、Timepix3等,加速电压从80 kV到300 kV不等。数据文件按scan_y, scan_x, k_y, k_x的四维立方体存储,按扫描行分块,使用Blosc2 zstd + bitshuffle压缩。每个数据集可能有多个变体(如不同区域或实验条件)。所有数据集均要求引用原始出版物,本仓库仅作为统一格式的重新托管平台。
ECLIPSE public 4D-STEM is a publicly available collection of 4D scanning transmission electron microscopy (4D-STEM) datasets. It compiles published experimental 4D-STEM data from other research groups and redistributes them in a unified, losslessly compressed HDF5 format (extension .e4d) with complete and validated calibration metadata. This dataset aims to provide a benchmark platform for reconstruction, compression, and denoising methods across various dose regimes, covering both ptychography and nanobeam diffraction modalities. Each file guarantees losslessness (the raw data is identical to the declared transformed cube), calibration completeness (energy, convergence semi-angle, scan step, detector sampling, scan-detector rotation, defocus, etc., are sourced and verified), and dose information (indicating whether it is electron counts, raw detector units, or preprocessed values). The dataset includes a fixed benchmark region of interest (benchmark_roi) to enable comparable benchmarks. The table of contents lists 19 datasets, covering multiple material systems (e.g., STO, NNO, La3Ni2O7, PdCuSi, polySi, PdH, SiGe, NVdiamond, AlAu, UCNP, SAEP, PBTTT, AlSPED, MOF, apoF, MAPbI3, MoS2MoSe2, Sb2S3), with dose ranges from approximately 6 e/Ų to 5.7e6 e/Ų, detectors including Merlin Medipix3RX, EMPAD, Gatan K3, Dectris ELA, 4D Camera, MerlinEM, Gatan CCD, Timepix3, etc., and accelerating voltages from 80 kV to 300 kV. Data files are stored as four-dimensional cubes (scan_y, scan_x, k_y, k_x), chunked along scan rows, and compressed using Blosc2 zstd + bitshuffle. Each dataset may have multiple variants (e.g., different regions or experimental conditions). All datasets require citation of the original publications; this repository serves only as a redistribution platform in a unified format.
