Unsupervised clustering and identification of marker reactions. A The HDBSCAN clustering of the UMAP coordinates based on the \(M_{W_{3}}\) (RAS values adjusted by TP along paths) shows a clear separation between GN and NB, as well as a separation of NB samples into two distinct groups. Round symbols represent GN and triangles are NB samples. B Box plot of normalized MYCN expression grouped by identified clusters. With a t-test statistic we demonstrate characteristic reactions per cluster. As an example, the box plot in C) shows the adjustment RAS values of reaction R11321 characteristically for cluster 1, D) the reaction R06038 characteristically for cluster 2, and E) the reaction R12960 characteristically for cluster 3. Boxes range from first to third quantile, the middle line indicates the median, the whiskers show the highest and lowest values no further than \(1.5*IQR\) from the hinge. Black dots represent the samples
