AutoFACT is a new automated tool for assigning biological functions to molecular sequences. This tool improves annotation accuracy and efficiency, aiding genomics research.

Area of Science:

  • Genomics
  • Bioinformatics

Background:

  • Assigning function to novel molecular sequences is crucial for genomics.
  • Traditional methods involve laborious similarity searches against databases.

Purpose of the Study:

  • To present AutoFACT, a fully automated and customizable tool for molecular sequence annotation.
  • To improve the efficiency and accuracy of functional annotation in genomics.

Main Methods:

  • AutoFACT analyzes nucleotide and protein sequences.
  • It integrates multiple BLAST reports from user-selected databases.
  • The tool assigns metabolic pathways, functional classes, Gene Ontology terms, and locus names.

Main Results:

  • AutoFACT achieves a low error rate of 1-2% for functional annotation.

  • It increases the number of informative annotations by approximately 50% compared to traditional methods.
  • Output is available in HTML, text, and GFF formats.

    • Conclusions:

    • AutoFACT is a valuable annotation tool for research groups with limited bioinformatics support.
    • The software is implemented in PERL and runs on LINUX/UNIX.
    • AutoFACT is accessible at http://megasun.bch.umontreal.ca/Software/AutoFACT.htm.
