During this course we will discuss basics and introduce state-of-the-art software-tools tailored for spatial omics and multiplexed image analysis. The most common workflows can be divided in three steps: (i) processing/preparing the images for cellular segmentation, (ii) extraction of the individual marker intensities for each cell which are subsequently used for cell phenotyping and (iii) neighborhood analysis to quantify interactions between the different cell types in the tissue. In this course we will visit each of these steps and present algorithms and software-tools used for processing, analysis and visualization of images and data. These tools include among others MCMICRO, SCIMAP, QuPath, Fiji and napari. The course will be delivered in 4 days (see program below). Each day we will have a presentations as well as hands-on sessions.


The course is intended for biologists and computational biologists who work with multiplexed images at a protein level (antibodies/immunofluorescence). Basic experience in programming with python, running programs through command line and fluorescence microscopy come in handy for this course but they are not necessary.


By the end of the course, participants will be able to:

  • Use the MCMICRO pipeline to perform image processing on multiplexed images.
  • Use QuPath, napari and Fiji to carry out annotations and visual quality control on images.
  • Do cell phenotyping and basic spatial analysis with SCIMAP.
  • Perform neighborhood analysis with e.g., MISTY and SpatialLDA.
  • Carry out a complete spatial analysis pipeline for multiplexed data, i.e., from image processing to cell segmentation, cell phenotyping and neighborhood analysis.
