protGear

protGear provides a generic three-step pre-processing framework for protein microarray data, incorporating multiple data pre-processing procedures to enable performance comparison across background correction, coefficient of variation (CV) based filtering, batch correction, and normalization.

Key Features:

• Background Correction: Implements background correction as the first pre-processing step for protein microarray data.
• CV-based Filtering: Applies coefficient of variation (CV) based filtering to assess and filter data quality.
• Batch Correction: Includes batch correction methods to address technical variation between experimental batches.
• Normalization: Provides normalization procedures to standardize data across samples and enable comparability.
• Multiple Procedure Comparison: Contains different data pre-processing procedures to allow direct comparison of their performance.

Scientific Applications:

• Protein Microarray Data Pre-processing: Enables systematic pre-processing of protein microarray data through a standardized three-step workflow.
• Pre-processing Method Evaluation: Facilitates comparative assessment of different background correction, filtering, batch correction, and normalization approaches.

Methodology:

The framework follows a three-step pre-processing pipeline: background correction, coefficient of variation (CV) based filtering, batch correction, and normalization.
