Inverting the matrix in Eq. 23 requires the absence of data point clusters and thus the necessity of the data minimization and uniformity as previously described in this section.
Additionally to the aspects of the quantification strategy and associated uncertainties, the interpretation of DGT based LA-ICP-MS chemical images is usually based on differences in data point clusters, which may have characteristic shapes, and not the interpretation of single data points.
While most of the data points fall below the isometric line of Ca + Mg/Na + K (Fig. 5d) and Cl + SO4/Na + K (Fig. 5e), almost all data points clustering above the Cl + SO4 = Ca + Mg line (Fig. 5f) indicate that neither evaporate weathering nor the carbonate weathering is the dominant process in the basin.
The experiment was performed with EMX1 spacer 1 and hp-sgRNA 2. Data points clustered along an axis have corresponding read counts of zero but were given a pseudocount for display purposes.

In pre-monsoon the data points cluster around the salinity apex with some exceptions, which are clustered towards high-alkali apex.
In the anion plot, while data points cluster around high HCO3− and low SO42− in winter, pre-monsoon is marked with SO42− enrichment replacing HCO3−.
This is because the correlation coefficient is very low (r 2 = 0.196), which is evident in Fig. 6, where most data points cluster in the low-Ca and low-F region.
As expected, a negative relationship was observed between increasing distance in bioactivity space and SAC score, with 60% of the data points clustered between SAC score ranges of 40 and 100 and distance ranges of 0.2 and 0.6.
The majority of analyte data points clustered near the origin, indicating insignificant variations in abundances, despite differences in the sample preparation protocols.
Response accuracy did not follow the normal distribution, with many data points clustered around the higher end of the 90 100% range.
