osra - 2.1.3-3 main

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) - 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 representation of the molecular structure images
encountered within that document.
