Low-temperature plasma mass spectrometry imaging of a chili pepper.  The data set contains raw data and the scripts to prepare the imzML file. The final imzML/ ibd files are also included.

The creation of the data is described in: Maldonado-Torres, Mauricio, José Fabricio López-Hernández, Pedro Jiménez-Sandoval, and Robert Winkler. 2014. “‘Plug and Play’ Assembly of a Low-Temperature Plasma Ionization Mass Spectrometry Imaging (LTP-MSI) System.” Journal of Proteomics 102C (March): 60–65. doi:10.1016/j.jprot.2014.03.003.

The data set was re-analyzed using R scripts, as reported in: Gamboa-Becerra, Roberto, Enrique Ramírez-Chávez, Jorge Molina-Torres, Robert Winkler, Enrique Ramírez-Chávez, Jorge Molina-Torres, and Robert Winkler. 2015. “MSI.R Scripts Reveal Volatile and Semi-Volatile Features in Low-Temperature Plasma Mass Spectrometry Imaging (LTP-MSI) of Chilli (Capsicum Annuum).” Analytical and Bioanalytical Chemistry 407 (19): 5673–84. doi:10.1007/s00216-015-8744-9.
