Figure 13From: Combining peak- and chromatogram-based retention time alignment algorithms for multiple chromatography-mass spectrometry datasetsScatter plots for BIPACE for the wheat dataset with alignment precision and recall. The retention time penalized variant of BIPACE using the dot product performs better than the plain variant using the cosine as the similarity function. The evaluation results of some instances report neither false positive nor false negative assignments, leading to precision and recall values of 1. These instances in general report only about one third of the maximum number of true positives reported for other parameterizations.Back to article page
