CDX (.cdx)

Background & Context

    • MIME type: chemical/x-cdxChemDraw Exchange format.
    • Used by CambridgeSoft Corporation's ChemDraw application to store molecular data.
    • Binary format.
    • Stores two-dimensional atomic coordinates, chemical bond information and metadata.

Import

  • Import["file.cdx"] imports a CDX file as a molecule.
  • Two-dimensional coordinates from the CDX file are stored in the molecule in the AtomDiagramCoordinates option value.
  • Use mol["AtomDiagramCoordinates"] to retrieve the coordinates from the imported molecule mol.
  • See the following reference pages for full general information:
  • Importimport from a file
    CloudImportimport from a cloud object
    ImportStringimport from a string
    ImportByteArrayimport from a byte array
