+Cardinal is an R package that implements statistical & computational tools for analyzing mass spectrometry imaging datasets.
+
+**Preprocessing steps:**
+
+- Smoothening: Smoothing of the mass peaks reduces noise and improves peak detection
+- Normalization: Normalization of intensities to total ion current (TIC)
+- Baseline reduction: Baseline  reduction removes backgroundintensity generated by chemical noise (common in MALDI datasets)
+- Peak picking: relevant peaks are picked while noise-peaks are removed
+- Peak alignment: mz inaccuracies are removed by alignment of same peaks to a common mz value
+- Peak filtering: removes peaks that occur infrequently, such as those which only occur in a small proportion of pixels
