Abstract
We present omniSpect, an open source web- and MATLAB-based software tool for both
desorption electrospray ionization (DESI) and matrix-assisted laser desorption ionization
(MALDI) mass spectrometry imaging (MSI) that performs computationally intensive functions
on a remote server. These functions include converting data from a variety of file
formats into a common format easily manipulated in MATLAB, transforming time-series
mass spectra into mass spectrometry images based on a probe spatial raster path, and
multivariate analysis. OmniSpect provides an extensible suite of tools to meet the
computational requirements needed for visualizing open and proprietary format MSI
data.
