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 the Name to Structure Home documentation. You can extend the document to structure conversion by creating a custom dictionary file.
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.
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.
As a commandline tool, you can use MolConverter for d2s conversion. Example:
Document to Structure 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.
For structures represented as images in PDF or Office documents, d2s can make use of several Image to Structure tools (also called Optical Structure Recognition or Chemical OCR ). When such a tool is installed and successfully recognizes an image, the chemical structure becomes part of the output of d2s; it can be visualized, edited, indexed and searched just like any other structure.
Currently, the supported Image to Structure tools are:
See configuration instructions to know how to make those tools recognized by d2s.
The "Document to Structure" license is needed.
