Document to Structure (d2s) Conversion

Document to Structure processes PDF, HTML, XML, text files and office file formats: DOC, DOCX, PPT, PPTX, XLS, XLSX, ODT. It recognizes and converts the chemical names (IUPAC, CAS, common and drug names), SMILES and InChI found in the document into chemical structures.

d2s conversion uses the name-to-structure converter. For the supported names and current limitation, see "Name to Structure Conversion" webpage. You can extend the document to structure conversion by creating a custom dictionary file.

d2s can be used via API, command line application (MolConverter), or MarvinView. Text mining can also be automatized by using d2s integrated into Knime or into Pipeline Pilot.

OCR and syntax correction

Chemaxon's d2s toolkit is able to correct several simple OCR and syntax error. For instance, given the incorrect name "3-rnethyl-l-me-thoxynaphthalene", it automatically corrects the name to "3-methyl-1-methoxynaphthalene" and generates the corresponding structure.

Document to Structure Conversion in MarvinView

Open a PDF file containing chemical names. MarvinView will display all the structures corresponding to the recognized names. The structures can then be saved, copy-pasted, opened in the MarvinSketch editor, ...

Document to structure conversion from command line

As a commandline tool, you can use MolConverter for d2s conversion. Example:

Converting "test.pdf" name file to MOL file:
```
 molconvert mol test.pdf -o test.mol
```

Structure conversion from OLE objects

D2s converts the chemical structures from OLE objects – created by various chemical sketchers such as Marvin, ChemDraw, ISIS/DRAW, SYMYX DRAW, and Accelrys Draw – embedded in office documents.

Chemical image recognition

If OSRA is installed on your computer, d2s will also convert the figures of compounds into editable chemical structures from PDF files.
