Quality control for maldi imaging mass spectrometry data. The output of this tool contains key values and plots of the imaging data as pdf. 
For additional beautiful heatmap images use the MSI ion images tool and to plot more mass spectra use the MSI massspectra tool. 

Input data: 3 types of input data can be used:

- imzml file (upload imzml and ibd file via the "composite" function) `Introduction to the imzml format <http://ms-imaging.org/wp/introduction/>`_
- Analyze7.5 (upload hdr, img and t2m file via the "composite" function)
- Cardinal "MSImageSet" data (with variable name "msidata", saved as .RData)
