MSI classification (version 2.10.0.0)
Input file as imzML (composite upload), Analyze7.5 (composite upload) or Cardinal MSImageSet saved as RData (regular upload)
Choose Yes if peak detection has already been done.
Choose no if your input is an Analyze7.5 or continuous imzML file
Three or four columns: x values, y values, response values, optionally fold values
This is the condition (pixel group) which will be classified
Each fold must contain pixels of all response groups and is used for cross validation
For cvapply multiple values are allowed (e.g. 1,2,3 or 2:5). Mininum is 1.
Can be used to generate a classification prediction on new data
Cardinal is an R package that implements statistical & computational tools for analyzing mass spectrometry imaging datasets. More information on Cardinal

This tool provides three different Cardinal functions for supervised classification of mass-spectrometry imaging data.

Input data

  • MSI 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
    • Analyze7.5 (upload hdr, img and t2m file via the "composite" function)
    • Cardinal "MSImageSet" or "MSImagingExperiment" saved as .RData
    • NA intensities are not allowed
    • duplicated coordinates will be removed
