Adelaide Proteomics Centre, Gastric Cancer in Mice, Processed MALDI-TOF MS

The dataset is an R file called GC.RData. This file consists of two data
frames, called dd and metaDF. dd contains 159 numeric observations of
protein intensity (from a mass spectrometer) on 1080 blood serum samples
from 40 mice. The different protein peak intensities are arranged and
labelled by mass/charge ratio. Some of the observations are missing, and
are recorded as NA values. The object metaDF contains metadata for each
of the 1080 samples which consists of a record of mouse replicate
number, mouse genotype group, mass spectrometer chip number, the sample
location on the chip, and the scanning order of the mass spectrometer's
laser on the chip.524Kb

本数据集为名为GC.RData的R语言数据文件。该文件包含两个数据框，分别命名为dd与metaDF。其中dd包含来自40只小鼠的1080份血清样本的159项蛋白质强度数值观测值，相关数据由质谱仪（mass spectrometer）采集，不同蛋白质峰强度按质荷比（mass/charge ratio）进行排布与标注。部分观测值存在缺失，以NA值进行记录。metaDF则收录了1080份样本的元数据（metadata），具体包括小鼠重复编号、小鼠基因型分组、质谱芯片编号、样本在芯片上的位置，以及质谱激光器在芯片上的扫描顺序，文件大小为524KB。
