Package: TargetSearch 2.7.1
Alvaro Cuadros-Inostroza
TargetSearch: A package for the analysis of GC-MS metabolite profiling data
This packages provides a flexible, fast and accurate method for targeted pre-processing of GC-MS data. The user provides a (often very large) set of GC chromatograms and a metabolite library of targets. The package will automatically search those targets in the chromatograms resulting in a data matrix that can be used for further data analysis.
