Cardinal is an R package that implements statistical & computational tools for analyzing mass spectrometry imaging datasets. `More information on Cardinal <http://cardinalmsi.org//>`_

This tool uses the Cardinal plot function to generate (zoomed in) mass spectra plots of mass-spectrometry imaging data.

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

Options:

- "single pixel": Returns a full mass-spectrum plot for one pixel, which is defined by its x- and y-coordinates

    - Enter the x and y coordinates of your pixel of interest
    - To have a visual control for the selected pixel, a heatmap of a mass of interest will be drawn. Two intersecting lines will show the pixel location. This procedure requires an mass of interest together with a mass range and for the lines the colour and type.
    - Additionally zoom into mass-spectra plots is possible by providing the minimum and maximum mass value to define the limits of the plot
- "All pixels of a sample": Returns a full average mass-spectrum plot with different colours for each subfile

    - This option only works on files that have previosly been combined in the combine tool
    - Additionally zoom into mass-spectra plots is possible by providing the minimum and maximum mass value to define the limits of the plot

Output:

- Pdf with the selected mass-spectra plots and additional control plots

Tip: 

- Corresponding peaklists with masses and their intensities can be obtained with the filtering tool option "ranges for x and y"
