cellXpress

cellXpress processes high-throughput cell images to extract quantitative phenotypic features and construct discriminative profiles for analysis of cellular responses to genetic and chemical perturbations.

Key Features:

• Efficient Image Handling: Optimized for processing large volumes of cell images from image-based screens with high throughput.
• Automated Cell Segmentation: Implements algorithms to segment cells and generate cell masks for downstream analysis.
• Quantitative Phenotypic Feature Measurement: Extracts a wide array of quantitative features that characterize cellular phenotypes from segmented images.
• Discriminative Profile Construction: Constructs discriminative profiles from measured phenotypic features to detect associations among perturbations.
• Visualization Capabilities: Provides visualization of segmented cell masks and quantitative feature values to support data interpretation.
• Integration with R Environment: Supplies library functions to load extracted features into the R computing environment for further analysis and visualization.
• Benchmarking and Performance: Includes performance comparisons against other bioimage analysis tools reporting speed, accuracy, and clustering performance metrics.

Scientific Applications:

• High-throughput phenotypic profiling: Analysis of cellular responses to genetic or chemical perturbations using image-based screens.
• Genome-wide gene knockdown screens: Processing and quantitative analysis of large-scale knockdown experiments to derive phenotypic signatures.
• Biomarker discovery and mechanism interrogation: Deriving discriminative profiles to identify potential biomarkers and investigate underlying mechanisms of perturbations.

Methodology:

The computational workflow comprises segmentation, feature extraction, discriminative profile construction, visualization, and performance benchmarking against other bioimage analysis tools.
