From BLAST to NGS Read Mapping: Alignment Tools in Bioinformatics
Master essential biological sequence alignment workflows from basic BLAST searches to advanced NGS read mapping platforms. Bridge the gap between raw sequencing outputs and downstream bioinformatics analysis using standard algorithmic tools.
Course Description
This intensive 5-day computational workshop is designed to provide hands-on mastery over foundational sequence alignment tools in bioinformatics. Participants will navigate the evolutionary spectrum of digital sequence matching, beginning with basic local alignment search tools (BLAST) and advancing to high-throughput Next-Generation Sequencing (NGS) read mapping frameworks. The curriculum covers the algorithmic logic behind pairwise alignments, database searching, and processing massive multi-omic datasets against reference genomes. By understanding how modern machine-readable data structures handle raw biological sequence files, you will learn to build structured and automated analysis pipelines. This program emphasizes practical analytical steps required to assess read quality, filter sequencing errors, and interpret complex computational outputs efficiently. Whether you are identifying conserved domains or setting up big-data alignment architectures, this session equips you with essential computational skills. Elevate your biological data research profile, master standard software ecosystems, and unlock the predictive capabilities of advanced genomics pipelines
