Details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

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
