Noise ReductionReduce random fluctuations in mass spectra while preserving true peak shapes as much as possible, improving spectral clarity.View Guide
Intensity NormalizationReduce differences in overall signal intensity between pixels, making mass-spectrometry signals from different spatial locations easier to compare.View Guide
Peak PickingIdentify major ion peaks from profile spectra and retain only their positions and corresponding intensities, reducing the amount of data for subsequent peak alignment and filtering.View Guide
Peak AlignmentMap nearby peaks from different pixels onto a common reference m/z axis so that the same ion can be compared directly across pixels.View Guide
Ion Image VisualizationView the spatial intensity distribution of a specified m/z value, and use TIC images and mass spectra to inspect processing results and tissue spatial characteristics.View Guide
KMeans Tissue Region SegmentationDivide pixels into several classes based on low-dimensional features, inspect the resulting spatial regions, and generate removal or retention masks after manual confirmation.View Guide
