+## OSRA: Optical Structure Recognition Application
+
+OSRA is a utility designed to convert graphical representations of chemical 
+structures, as they appear in journal articles, patent documents, textbooks, 
+trade magazines etc., into SMILES (Simplified Molecular Input Line Entry 
+Specification - see http://en.wikipedia.org/wiki/SMILES) or 
+SD files - a computer recognizable molecular structure format. 
+OSRA can read a document in any of the over 90 graphical formats parseable by 
+ImageMagick - including GIF, JPEG, PNG, TIFF, PDF, PS etc., and generate 
+the SMILES or SDF representation of the molecular structure images encountered 
+within that document.
+
+Note that any software designed for optical recognition is unlikely to be 
+perfect, and the output produced might, and probably will, contain errors, 
+so curation by a human knowledgeable in chemical structures is highly recommended.

+The wrapper comes with an automatic installation of all dependencies through the
+galaxy toolshed.
