The Ribosomal Database Project (RDP) has introduced several improvements and new tools for rRNA analysis. The RDP now provides quality-controlled bacterial and archaeal small subunit rRNA alignments and analysis tools, including an improved alignment strategy using the Infernal secondary structure-aware aligner, which offers faster processing and more consistent, higher-quality alignments. A new Pyrosequencing Pipeline supports ultra-high-throughput rRNA sequencing data, automating data processing and simplifying complex analyses. The pipeline includes tools for taxonomy-based and taxonomy-independent community analysis. Additionally, a new Taxomatic visualization tool allows for rapid identification of taxonomic inconsistencies and suggests corrections. The RDP also introduces a new Class Assignment Generator, an educational tool for teaching rRNA analysis, providing instructors with lesson plans and individualized teaching materials. These enhancements are part of the RDP's ongoing efforts to improve user experience and support in rRNA research.The Ribosomal Database Project (RDP) has introduced several improvements and new tools for rRNA analysis.
