SignalViewer

SignalViewer analyzes cDNA microarray images to quantify and interpret genome-wide gene expression from image data.

Key Features:

• Automated alignment: Provides automated alignment processes for cDNA microarray images.
• Minimal manual intervention: Enables exploration of image data with reduced requirement for manual input.
• Method transparency: Exposes and reports limitations and assumptions used in image analysis.
• Reproducibility and reliability: Reduces human-induced variability in microarray quantification to support reproducible results.
• Scalability: Processes large microarray image datasets for genome-wide expression analysis.
• Workflow streamlining: Streamlines steps from image acquisition to data interpretation.

Scientific Applications:

• Differential expression analysis: Identifies differentially expressed genes across conditions using cDNA microarray images.
• Genome-wide expression profiling: Supports comprehensive gene expression profiling across treatments or conditions.
• Disease mechanism studies: Aids investigation of molecular-level disease mechanisms via expression pattern analysis.
• Therapeutic response evaluation: Evaluates responses to therapeutic interventions through comparative expression analysis.

Methodology:

Automated alignment of microarray spots and computational processing of image data with explicit reporting of analysis assumptions and limitations.
