TotalRepeats

Rapid de novo identification, masking, visualization and clustering of repetitive sequences.

Tool for rapid de novo identification, masking, visualization and clustering of all repeated sequences at the genomic scale. Detects direct and inverted repeats, microsatellites, telomeres, and complex higher-order repeat structures.

Alternative: For unlimited genome sizes, use the command-line TotalRepeats Java application.

  • Detected repeats: Direct and inverted repeats, perfect and imperfect microsatellites, telomere repeats, tandem repeats, complex patterns
  • Size limit: Theoretically unlimited; practical limit ~100 MB due to browser RAM constraints
  • Input format: sequence(s) can be pasted or uploaded as a file in FASTA format or retrieved sequence (NCBI’s accession, e.g. PQ145547) from NCBI’s "nuccore" nucleotide database.
Upload or paste sequence(s) in FASTA format:

Detection Parameters

Quick Help
  • Paste/upload FASTA or retrieve by accession; for large inputs prefer files to reduce browser overhead.
  • Use the visualization controls (canvas size, export/save) to inspect repeat blocks and masked sequence.
