Get Sequences

NCBI GenBank Import can be used to retrieve nucleotide or amino acid sequences from NCBI's GenBank repository by submitting a list of accession or GI numbers.

Quick Start

  • To use NCBI GenBank Import, upload your list of identifiers in plain text/.txt format. Select the list and chose the amount of information to be stored in the sequence header of the output file. Options are:
    • Minimal: GI number only,
    • Species: GI number, species name and taxon ID,
    • Short: GI number and shortened species name,
    • Full: GI number, accession, version, species name and taxon ID.
      If necessary, enter a length difference threshold to exclude sequences that are longer or shorter than the median length. Leave blank to retrieve all sequences.
