There are three directories. Description these directories are provides in the files "Read Me 1" and "READ Me 2".The first : "raw_data" contains the laser-induced spectroscopic data measured on the blood plasma samples of 46 healthy, 64 infected donors and 40 blinds donors provided in alphabetical order. The details on the way these spectroscopic data were obtained is described in the manuscript. The file "READ ME 1" describes the content of the directories and files.The second "reductions_matrix" contains files describing the Z-score analysis for outlier removal, resulting in "cleaned" spectra for all patient samples including the mean spectra for every patient sample. The latter were compiled into a spreadsheet ("df_matrix__Covid-19-blood-plasma__mean_norm__noback__@zsc=1.0_all_2022-10-20__pos86.xlsx") and is provided in the "reductions_matrix" directoryThe third: "ZSC=1.0" contains the files "figures", "identifications", and "reductions". The directory "figures" contains a comprehensive collection of figures that were created during the statistical outlier removal and spectral analysis for all patient samples. "identifications" contains information and results regarding elemental line identifications based on comparisons with NIST-ASD data. The file "READ ME 2" describes the content of the directories and files

本数据集包含三个目录，相关目录与文件的说明详见"Read Me 1"与"READ Me 2"两份文件。
第一个目录为raw_data（原始数据目录），其内存储了针对46名健康供者、64名感染供者及40名盲测供者的血浆样本所测得的激光诱导光谱数据（laser-induced spectroscopic data），所有样本均按字母顺序排列。上述光谱数据的采集细节已在研究手稿中详述。"READ ME 1"文件用于说明本数据集各目录及文件的具体内容。
第二个目录为reductions_matrix（降维矩阵目录），其内存储了用于异常值剔除的Z分数分析（Z-score analysis）相关文件，经分析后可得到所有供者样本的“清洁化”光谱，同时包含每名供者样本的平均光谱。上述平均光谱已汇总至电子表格"df_matrix__Covid-19-blood-plasma__mean_norm__noback__@zsc=1.0_all_2022-10-20__pos86.xlsx"中，且该表格已存放于"reductions_matrix"目录内。
第三个目录为"ZSC=1.0"，其内包含"figures（图表子目录）"、"identifications（谱线识别子目录）"与"reductions（降维处理子目录）"三个子目录。其中"figures"目录存储了针对所有供者样本开展统计异常值剔除与光谱分析过程中生成的全套图表；"identifications"目录存储了基于与NIST-ASD数据比对得到的元素谱线识别相关信息与结果。"READ ME 2"文件用于说明该目录下各子目录及文件的具体内容。
