We developed a website using the ASIAN system to infer biological networks from large datasets. This tool aids in analyzing gene expression profiles and identifying gene clusters.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Systems Biology

Background:

  • Gene expression data analysis often involves redundant information.
  • Inferring biological networks is crucial for understanding complex cellular processes.
  • Previous methods for genomic-scale gene expression analysis have limitations.

Purpose of the Study:

  • To create a user-friendly website for network inference.
  • To integrate existing methods for analyzing gene expression profiles.
  • To provide tools for network construction with clustering capabilities.

Main Methods:

  • Utilized the Automatic System for Inferring A Network (ASIAN).
  • Applied the graphical Gaussian model for network inference.
  • Incorporated hierarchical clustering and cluster boundary estimation.
