SpacerMap

CRISPR Visualization

i

Visualize CRISPR spacer distributions across arrays and explore their evolutionary relationships using multiple sorting methods.

Features

  • Spacer distribution
  • Array cluster
  • High-resolution image export

Input

  • Paste pre-numbered spacer arrays
  • Upload TXT, FASTA or JSON files

CRISPRPhylo

Phylogenetic Analysis

i

Infer CRISPR spacer-based phylogenetic trees using deep learning and graph-based methods to support evolutionary studies.

Features

  • Multiple tree inference methods
  • Tree visualization
  • Newick format export

Input

  • Paste spacer CSV data directly
  • Upload CSV or JSON format

NCBI Sequence Fetcher

Retrieve nucleotide or protein sequences by accession or UID, inspect sequence metadata, and download selected records.

  • Single or batch accession lookup
  • FASTA, metadata and ZIP downloads
  • Sequence preview and failed-ID retry
Open NCBI Sequence Fetcher

CRISPR Detection & Processing

Use one compact workflow for input sequences and existing CRISPRCasFinder output.

Input Sequence→Run CRISPRCasFinder / Import→Review & Process→Export / Continue

The page will parse, validate, filter and rename results, then convert them for SpacerMap, CRISPRPhylo and downstream analyses.

Open Detection & Processing →

Figure Composer

Align SpacerMap and CRISPRPhylo outputs by sample name, tune panel widths and export a single integrated figure.

  • Sample-aware SpacerMap and tree alignment
  • Independent panel width controls
  • SVG, PDF and PNG export
