BBTools Interactive Web Services

These web-based tools provide interactive interfaces for popular BBTools programs. No installation required - just paste or upload your sequences and get instant results!

Note: Services marked with 🚧 UNDER CONSTRUCTION are in development and not yet publicly available. The interfaces are ready for preview, but backend servers have not been deployed.

QuickClade

Rapid taxonomic classification of genomic sequences using pre-computed k-mer databases. Identify organisms in seconds!

BBSketch

Fast sequence similarity search against reference databases. Find the closest matching organisms for your sequences.

Taxonomy Lookup

Search and explore the NCBI taxonomy tree. Find taxonomic IDs, lineages, and relationships between organisms.

Alignment Visualizer

Interactive visualization of sequence alignments. Compare different alignment algorithms and see their behavior.

SAM Format Decoder

Decode SAM/BAM alignment lines and flags. Paste any SAM line to see detailed explanations of all fields, flags, CIGAR operations, and optional tags.

Assembly Statistics

Calculate comprehensive assembly statistics including N50, L50, GC content, scaffold counts, and quality metrics.

Translate6Frames

Translate DNA/RNA sequences to amino acids in all six reading frames. Identify potential protein-coding regions.

CallGenes

Prokaryotic gene prediction for bacteria, archaea, viruses, and mitochondria. Find genes, rRNAs, and tRNAs.

Random Genome Generator

Generate synthetic genomes with specified characteristics for testing and educational purposes.

Genome Mutator

Simulate genome mutations with controlled substitution, insertion, and deletion rates. Test variant callers.

Reverse Complement

Quickly reverse-complement DNA/RNA sequences. Perfect for primers and probes. Supports all IUPAC codes and works entirely in your browser!

K-mer Cardinality Estimation

Estimate unique k-mer counts using LogLog probabilistic algorithm. Privacy-preserving client-side processing for quality assessment and genome analysis.
