Colon Data - Lipid MSI from Chronic Pain Model (Rat)

Rat model of comorbid visceral pain. Colon tissues swiss-rolled in 2% gelatin. Cryosections at 12 um thickness. Norharmane matrix, negative ion mode lipid scans by MALDI-MSI at 50um spatial resolution. Converted from native file structure to the common file format, .imzML. Compressed zip folders contain both the .ibd and .imzML files. Data used in: Kasun Pathirage, Aman Virmani, Alison Scott, Richard Traub, Robert Ernst, Reza Ghodssi, Behtash Babadi, and Pamela Abshire.
