Detection of Low-Quality Peaks in Untargeted Metabolomics Data

Utilizes 11 peak quality metrics and 8 diverse machine learning algorithms to build a classifier for the automatic assessment of peak integration quality of peaks from untargeted metabolomics analyses. The 12 peak quality metrics were adapted from those defined in the following references: Zhang, W., & Zhao, P.X. (2014) Toghi Eshghi, S., Auger, P., & Mathews, W.R. (2018) .
