Two freeware programs, Bullfrog and Spot, were developed for analyzing gene-expression data from Affymetrix and cDNA arrays, respectively. These tools simplify data filtering and quality assessment to aid in biological discovery.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Gene Expression Analysis

Background:

  • Gene expression analysis is crucial for understanding biological processes and phenotypes.
  • Analyzing large gene expression datasets can be complex and computationally intensive.
  • Existing tools may not offer intuitive interfaces or comprehensive quality assessment for diverse array types.

Purpose of the Study:

  • To develop user-friendly, HTML-based software for analyzing gene expression data.
  • To provide efficient data filtering and normalization tools for Affymetrix and cDNA arrays.
  • To facilitate the identification of genes associated with specific biological processes or phenotypes.

Main Methods:

  • Development of two distinct freeware programs: 'Bullfrog' for Affymetrix oligonucleotide arrays and 'Spot' for custom cDNA arrays.

  • Implementation of an intuitive, HTML-based graphical user interface for data analysis.
  • Inclusion of a background subtraction and normalization module for cDNA arrays with detailed quality assessment reports.

    • Main Results:

    • Successful creation of 'Bullfrog' and 'Spot' programs for gene expression data analysis.
    • The programs offer intuitive data filtering capabilities via an easy-to-use interface.
    • A dedicated program for cDNA arrays includes background subtraction, normalization, and data-quality assessment reporting.

    Conclusions:

    • The developed freeware programs enhance the analysis of gene expression data.
    • These tools streamline the process of identifying genes involved in biological functions.
    • Accessible bioinformatics tools like Bullfrog and Spot can accelerate biological research and discovery.
