OSRA is a utility designed to convert graphical representations of chemical structures, such as they appear\nin journal articles, patent documents, textbooks, trade magazines etc., into SMILES.<br /><br /></p>\n\n  <p>OSRA can read a document in any of the over 90 graphical formats parseable by ImageMagick (GIF, JPEG, PNG, TIFF, PDF, PS etc.) and\ngenerate the SMILES representation of the molecular structure images encountered within that document.</p>\n</blockquote>\n\n<p>The email does not give any information on the fail rate, but the demo they provide via the\n<a href=\"http://cactus.nci.nih.gov/cgi-bin/osra/index.cgi\">webinterface</a> does show some minor glitches (the bromine is not recognized):</p>\n\n<p><img src=\"/assets/images/osra.png\" alt=\"\" /></p>\n\n<p>The source reuses <a href=\"http://openbabel.sf.net/\">OpenBabel</a> and uses the GPL license. The value equal to that of text mining tools like\n<a href=\"https://chem-bla-ics.linkedchemistry.info/2006/06/22/text-mining-for-chemistry-using-oscar3.html\">OSCAR3 <i class=\"fa-solid fa-recycle fa-xs\"></i></a>,\nand together they sounds like the Jordan and Pippen of mining chemical literature.</p>",
