Description of the biological application
Phenotypic profiling attempts to summarize multiparametric, feature-based analysis of cellular phenotypes of each sample so that similarities between profiles reflect similarities between samples. This image set provides a basis for testing image-based profiling methods wrt. to their ability to distinguish the effects of small molecules.
The images are of U2OS cells treated with each of 1600 known bioactive compounds and labeled with six labels that characterize seven organelles (the “Cell Painting” assay).
This pilot experiment consists of 20 plates. Each plate has 384 wells and each well has 9 fields of view for a total of 69,120 fields of view. Each field was imaged in five channels (detection wavelengths), and each channel is stored as a separate, grayscale image file, so there are 345,600 image files in 16-bit TIFF format. The images were taken at 20X magnification (0.656 μm/pixel).
The images are provided in 100 zip archive files, one for each combination of plate and channel. There is a list of the URLs of all 100 files to facilitate downloading the entire image set in batch.

Nucleus segmentation annotations
Part of this dataset has been used for nucleus segmentation research, and a subset of 200 images have been selected for manual annotation of nucleus shapes. These annotations and more details about the segmentation problem can be found in the BBBC039 dataset.
