ADAP-GC是一种自动计算管道,用于非靶向的、基于gc - ms的代谢组学研究。它将原始质谱数据作为输入,并执行一系列数据处理步骤,包括构建提取的离子色谱图,检测色谱峰特征,共洗脱化合物的反卷积以及跨样品的化合物排列。尽管从原始版本到2.0版本在提取代谢物信息用于鉴定和定量方面的准确性有所提高,但aap - gc 2.0需要对许多参数进行适当的规范,并且在提取低浓度化合物信息方面存在困难。为了克服这两个限制,开发了ADAP-GC 3.0,以提高化合物检测的鲁棒性和灵敏度。在本文中,我们报告了这些目标是如何实现的,并将ADAP-GC 3.0与代谢组学社区广泛使用的其他三种软件工具(包括ChromaTOF, AnalyzerPro和AMDIS)进行了比较。
ADAP-GC is an automated computational pipeline for untargeted, GC-MS-based metabolomics studies. It takes raw mass spectrometry data as input and carries out a sequence of data processing steps including construction of extracted ion chromatograms, detection of chromatographic peak features, deconvolution of co-eluting compounds, and alignment of compounds across samples. Despite the increased accuracy from the original version to version 2.0 in terms of extracting metabolite information for identification and quantitation, ADAP-GC 2.0 requires appropriate specification of a number of parameters and has difficulty in extracting information of compounds that are in low concentration. To overcome these two limitations, ADAP-GC 3.0 was developed to improve both the robustness and sensitivity of compound detection. In this paper, we report how these goals were achieved and compare ADAP-GC 3.0 against three other software tools including ChromaTOF, AnalyzerPro, and AMDIS that are widely used in the metabolomics community.
