Genome Biology, 2006) to perform nuclear and cell annotation on melanoma histopathology slides. CellProfiler: image analysis software for identifying and quantifying cell phenotypes. We also post guided exercises as part of our educational outreach effort. This pipeline was developed using the publicly available CellProfiler software (Carpenter AE et al. Simple nuclei identification tutorial ( sample data) (courtesy of the German BioImaging network) These modules are crucial for any CellProfiler pipeline because they define how images are loaded and organized in CellProfiler for downstream analysis. Performing a colocalization assay ( relevant example pipeline) A tutorial to introduce you to four modules in CellProfiler Images, Metadata, NamesAndTypes, and Groups (collectively known as the Input modules). Using the Worm Toolbox for image analysis of C. Identifying and measuring cells: Cytoplasm-nucleus translocation assay ( relevant example pipeline)Ĭalculating and applying illumination correction for images ( relevant example pipeline) Identifying, measuring, and classifying yeast colonies ( relevant example pipeline) Using the Input modules in CellProfiler 2.1: Using CellProfiler for Quantitative Image Analysis The NIH has published a introductory chapter of “best practices” for image-based high-content screening (in which CellProfiler is mentioned) as part of the Assay Guidance Manual, and our group has published a more advanced follow-up chapter on image analysis methods. 1) StartingModules to initialise the pipeline, 2) tools performing the analysis ( Fig. Our introduction to automated image analysis principles and practicalities is published as an educational article at PLoS. CellProfiler is a free, open source program that allows researchers to automate image analysis and collect large amounts of phenotypic data relatively easily. Technical descriptions of CellProfiler and CellProfiler Analyst software can be found in our papers while more written tutorials can be found on the CellProfiler GitHub page. ![]() Quantitative image analysis of gamma-H2AX. Optionally, the associated information about the images (metadata). CellProfiler pipeline for foci analysis in DAPI-FITC images Applied in : J.E. We won’t be using the results data from this run so which set of images is not important, what matters is that we can run the pipeline workflow from start to end. The pipeline, which is a series of modules put together to analyze a set of images. Open up the CellProfiler pipeline you previously used to perform the analysis, then remove all but a single set of images. Visit our YouTube playlist for video tutorials on CellProfiler, CellProfiler Analyst, segmentation strategies, how to construct pipelines, and much more. In CellProfiler, a projectis comprised of two elements: An image file listwhich is the list of files and their locations that you select as candidates for analysis.
