Fig. 5From: Mass recalibration for desorption electrospray ionization mass spectrometry imaging using endogenous reference ionsExample of the effect of recalibration on the quality of an assigned metabolites’ spatial distribution by METASPACE for the ORBITRAP colon ES− 2. The original dataset shows a band of missing intensities caused by the masses’ nonlinear distribution across the pixels, which is corrected in the recalibrated dataBack to article page
