EZcircular Instructions


EZcircular takes a mitochondrial genome BED file and a reference FASTA sequence to:

  1. Validate and parse the BED annotation.
  2. Append 100 Ns and an artificial BED feature if the genome is linear.
  3. Locate the starting gene and reorder the FASTA sequence.
  4. Generate an updated BED file with correct coordinates.
  5. Produce circular or linear genome maps based on the topology.

Output example: Download

  • BED file: Describe your mitochondrial genome annotation with exactly 6 fields: chrom, chromStart, chromEnd, name, score, strand. Must be in BED format (.bed, .txt), GFF not supported. Convert with gff2bed if needed.
  • FASTA file: Containing only the reference genome sequence (.fasta, .fa, .fsa, .fas, .fna, .ffn, .faa, .frn).
  • If the genome is incomplete, select linear topology.
