Cardinal is an R package that implements statistical & computational tools for analyzing mass spectrometry imaging datasets. More information on Cardinal
This tool uses the Cardinal image function to plot the intensity distribution of m/z features 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
Tabular file with m/z values:
One column with numeric m/z values (without empty fields or letters), another column with names for the m/z (m/z column can also be used as name)
The file is allowed to have any column names as header (in this case set "Tabular file contains a header line" to yes)
m/z features outside the m/z range of the input file are ignored
m/z name 100.0 analyte1 100.01 analyte2 100.02 analyte3 ... ...
