ATS Spotted MSI Analysis with Matlab

Abstract

Samples are placed on a surface using an acoustic transfer system (ATS). This results in one ore more small droplets on a surface. Typically there are hundreds to thousands of these droplets arrayed in a regular coordinate system. The surface is analyzed using mass spectrometry imaging (MSI) and at each position, one or more mass spectra are recorded. The purpose of the software is to help the user assign locations to the spots and build a report for each spot.
