DIAMOND is a BLAST-compatible local sequence aligner for protein and translated DNA searches, designed for high-performance analysis of large sequence data. It also supports protein sequence clustering and taxonomic classification with output in BLAST pairwise, tabular, and XML formats.

Use cases

• align protein sequences against a reference database
• run BLAST-like searches 100x faster on big sequence data
• cluster large protein sequence datasets
• classify sequences taxonomically
• align long reads with frameshift-aware alignment
• analyze metagenomic sequencing data

When to choose

• you need BLAST-compatible alignments but BLAST is too slow for your data volume
• you are processing large-scale sequencing or metagenomic datasets
• you need protein sequence clustering that scales across compute nodes
• you want low resource requirements that run on a desktop or laptop

When to avoid

• you need the exact sensitivity or feature set of NCBI BLAST for small queries
• you require a graphical interface rather than a command-line tool
• your task is nucleotide-only alignment without translated searches
