Bioinformatics Toolbox provides a set of functions for mass spectrometry data analysis. These functions enable preprocessing, classification, and marker identification from SELDI, MALDI, LC/MS, and GC/MS data. Preprocessing functions include baseline correction, smoothing, calibration, and resampling. You can align raw spectra data using the M/Z axis and perform retention-time alignment on LC/MS and GC/MS data. You can plot multiple spectra simultaneously.
You can smooth, align, and normalize spectra and then use classification and statistical learning tools to create classifiers and identify potential biomarkers.
