Identifying unknown samples based on peak data

This tutorial shows the user how to create and validate an identification project based on a set of reference samples and how to use this reference set to identify unknown samples. Here, we use peak data, but any type of data and also combinations of data can be used in an identification project. The functionality described in this tutorial is part of the Classifiers and Identification module.


Spectrum types (or spectra) share some features with fingerprints, but are specifically designed to hold and process e.g. mass spectrometry data such as MALDI TOF MS, LC MS, ESI and SELDI.
