CLiDE Professional

Extract large amounts of structures from documents by a simple mouse click


CLiDE Professional is a chemistry intelligent equivalent of an Optical Character Recognition (OCR) software tool. Just as an OCR tool can recognize characters from scanned images of printed text, CLiDE Professional can recognize structures which can be exported into computer-readable file formats.

CLiDE Professional saves users hours of redrawing structures from printed material, as it transforms 'structure diagrams' into 'real structures'. CLiDE Professional is the enterprise version of CLiDE Standard with the capability to process a large amount of structures in a simple mouse click.


  • Is an easy-to-use document viewer
  • Has a contemporary user interface modelled on Acrobat Reader
  • Opens documents of the following types:
    • PDF (Portable Document Format)
    • DOC (Word 2003)
    • DOCX (Word 2007 and 2010)
    • HTML (HyperText Markup Language)
  • Opens images files of several types, including
    • BMP (Bitmap Image File)
    • GIF (Graphical Interchange Format File)
    • JPEG, JPG, JPE, JIF (JPEG Image File)
    • PBM (Portable Bitmap Image)
    • PGM (Portable Greymap)
    • PNG (Portable Network Graphics)
    • PNM (Portable Any Map Image)
    • PPM (Portable Pixmap Image File)
    • TIFF, TIF (Tagged Image File Format)
    • XBM (X Windows Bitmap)
    • XPM (X Windows Pixmap)
  • Extracts structures from structure diagrams
  • Attempts to interpret generic structures
  • Detects interpretation errors
  • Chemical extraction can be done interactively via the user interface
  • Provides split view for easy comparison of source and extracted structures
  • Indicates structures that have any abnormalities (including recognition errors and valence violations)
  • Supports displaying super atoms in expanded and contracted form
  • Provides a set of options
    • to annotate structure parts e.g. non-interpreted atoms or valence-violated atoms
    • to control the recognition process
    • to select which chemical editor to use
    • to control the information saved into exported files
  • Supports structure editing directly via
    • ChemDraw
    • Accelrys Draw (formerly Symyx Draw and ISIS Draw)
    • Marvin Sketch
    This allows you to correct any recognition errors present in the extracted structures
  • Saves structures in the following formats:
    • MDL Molfile
    • MDL SDfile
    • MDL RGfile
    • CDX (ChemDraw)
    • CML (Chemical Markup Language)
    • MRV (ChemAxon Marvin Document)
    • XML (Extensible Markup Language)
  • Supports multi-session document analysis. This can be done by saving the extraction results into XML file format which can be reloaded at a later time in order to continue reviewing and exporting structures
  • Supports grouping structures so that multiple structures can be edited
  • Supports deleting structures so that unwanted structures can be excluded


Supported operating systems:

  • Windows 8, 7, Vista, XP
  • Mac OS X
  • Linux
