Direct three-dimensional mass spectrometry imaging of low molecular weight compounds in kiwi fruit with laser ablation remote atmospheric pressure photoionization/chemical ionization (LARAPPI/CI)

The materials include documentation of experiments on three-dimensional mass spectrometry imaging (3D MSI) of metabolites in kiwi fruit tissues using the LARAPPI/CI (Laser Ablation Remote Atmospheric Pressure Photoionization/Chemical Ionization) platform coupled with an ultrahigh resolution QToF (quadrupole-time-of-flight) mass spectrometer.Files contain four parts of raw 3D MSI data from a kiwi fruit, which can be opened using an open-source R package that is freely available. The original data has been split into four ZIP archive files, each of which can be accessed with free software. After downloading all the parts, the file with the .zip extension initiates the extraction process, combining all the parts into a single file.
