Core Event: Introduction of vConTACT3 for Viral Genome Analysis
vConTACT3 is a novel tool designed for the classification and analysis of viral genomes. It utilizes user-provided genomes to predict open reading frames (ORFs) and clusters them based on varying identity thresholds. This process enhances the understanding of viral taxonomy and relationships among different viral genomes.
Methodology of vConTACT3
The vConTACT3 framework begins with the submission of user genomes, which are analyzed to predict ORFs using the Prodigal software. These ORFs are then clustered at five distinct identity thresholds: 30%, 40%, 50%, 60%, and 70%. Each clustering identity generates a separate protein cluster (PC) profile. The profiles are processed through a component known as the "Resolver," which constructs a distance matrix for each profile based on a selected metric, typically the square root.
This distance matrix is transformed into a network annotated with genome information, including unique genes and proximity to reference sequences. The network undergoes filtering based on the minimum number of shared genes required between genomes, and it can be repaired to ensure connectivity among components. Users have the option for a high-accuracy repair, which, while more computationally intensive, offers greater precision.
The final stage involves predicting virus realms associated with each genome, utilizing network connections and shared protein clusters. The output from this process is then compared against reference sequences to calculate performance metrics, ultimately integrating various outputs into user-friendly formats such as Cytoscape and interactive HTML networks.
Why It Matters: Implications for Viral Research
The introduction of vConTACT3 represents a significant advancement in the field of virology, providing researchers with a robust tool for classifying and understanding viral genomes.
