The study presents a comprehensive evaluation of gene regulatory network inference methods using the DREAM5 challenge, which tested over thirty methods on four organisms and in silico data. The results show that no single method performs optimally across all datasets, but integrating predictions from multiple methods yields robust and high-performance networks. The study constructs high-confidence networks for E. coli and S. aureus, each with ~1700 transcriptional interactions at ~50% precision. Experimental validation of 53 novel interactions in E. coli confirmed 23 (43%). The study highlights the importance of community-based methods for robust network inference, as they outperform individual methods across diverse datasets. The results demonstrate that integrating predictions from multiple inference methods improves accuracy and reliability, especially for complex regulatory networks. The study also shows that the performance of individual methods varies significantly, and that combining diverse methods enhances overall performance. The study provides a public resource for benchmark datasets and team predictions, along with a web interface for applying top-performing inference methods. The findings suggest that community-based approaches are powerful and robust for gene regulatory network inference, and that further improvements in individual methods can enhance overall performance. The study also emphasizes the importance of considering experimental conditions and data diversity in network inference. The results indicate that while methods perform well for prokaryotic datasets, eukaryotic datasets pose greater challenges. The study concludes that community-based methods are essential for accurate and reliable gene regulatory network inference.The study presents a comprehensive evaluation of gene regulatory network inference methods using the DREAM5 challenge, which tested over thirty methods on four organisms and in silico data.
