How to use:
- Select the file you want to process or enter a URL (http://...) pointing to an image and click the "Submit" button.
Any of the over 90 image formats recognized by ImageMagick including GIF, JPEG, PNG, PDF, PS and TIFF can be processed.
- Correct recognized structures using the JME Molecular Editor.
- Preview the 3D structure if necessary. Note - the generated 3D image is for demonstration purposes only, e.g. to help disambiguate bridge bonds etc. OSRA only generates the connection table, not the 3D coordinates.
- Click on the "Get SMILES" button to obtain the SMILES of the structure. You can then use the provided live links
to convert SMILES to other chemical formats or to locate the structure in Chemical Structure Lookup Service.
"Get SD File" button will be active only after you have checked/edited all the structures recognized in the document.
You can use it to download the SD file containing all the recognized structures.
