VAP

VAP generates aggregate and individual signal profiles across genomic features such as genes, annotations, and user-defined regions of interest to represent and analyze genome-wide sequencing data such as ChIP-Seq.


Key Features:

  • Profile Generation: Creates signal intensity representations as aggregate curves and as individual heatmaps over genetic features such as genes and annotations.
  • Absolute and Relative Methods: Supports both absolute and relative profiling methods for signal aggregation and comparison.
  • Graphical Outputs: Produces graphical outputs (aggregate profiles and heatmaps) for visualization of signal distributions.
  • Subgrouping by Flanking Annotation Orientation: Enables subgrouping of regions based on the orientation of flanking annotations.
  • Statistical Measures: Includes statistical measures within outputs to support comparisons between groups or datasets.
  • Memory Management for Large Datasets: Controls memory usage to handle large genomic datasets efficiently.

Scientific Applications:

  • ChIP-Seq analysis: Analyzes ChIP-Seq signal intensity across genetic features to assess binding or enrichment patterns.
  • Gene regulation and functional genomics: Generates aggregate and individual profiles to support discovery and comparative analyses in gene regulation and functional genomics studies.

Methodology:

Systematic representation of genomic data through user-defined groups of regions of interest using absolute and relative methods to generate aggregate curves and heatmaps, with subgrouping by flanking annotation orientation, embedded statistical measures, and memory-control techniques for large datasets.
