Fernanda Garcia-Fossa & Anne Carpenter In a typical quantitative microscopy experiment, biologists choose fluorescent biomarkers and measure particular features (that is “metrics”) that they hypothesize will be perturbed in their samples. But in image-based profiling, you aim to let the cells tell...

Pearl V. Ryder In the previous posts in this series, I explained how I approached an image analysis project to segment extracellular fibrils, giving an overview of the project (Part I), showing how I removed bright debris from the images (Part II), enhanced the fiber brightness and reduced...

Pearl V. Ryder In the first post of this series, I gave an overview of this project and explained how I imported the data into CellProfiler. If you’d like to follow along in CellProfiler, the pipeline and images for this project are available here. Now that the images have been imported, I could...

Mario Costa Cruz If you have color images stained with light-absorbing dyes, the UnmixColors module might be able to separate the dyes into separate channels so that they can be analyzed separately. Separating the dyes into channels can be a difficult task with traditional methods such as split...

Authors: Beth Cimini, John Kitchin, Andrew Rosen, and Anne Carpenter What is the COA form? NSF requires you to report all “Co-authors on any book, article, report, abstract or paper with collaboration in the last 48 months” in Table 4 of the COA form, for certain people (e.g. PI, Co-PI, Senior/Key...

Pearl V. Ryder The Robust Background algorithm is a powerful algorithm for automatically setting thresholds to segment objects of interest when your image contains mostly background. However, since it contains the largest number of tunable parameters of any thresholding algorithm in CellProfiler, it...
