OSRA 2.1.0 released
Just got this email
I am glad to announce the release of OSRA 2.1.0. OSRA (Optical Structure Recognition Application) is a tool for converting images of molecules into SDF, SMILES and many other chemical formats. Images can be pictures of single molecules or complete PDF documents with multiple pages of text and graphics. In addition to molecules OSRA can also recognize reactions, and, starting with this version, simple polymers.
The improvements in this version: - Significantly improved recognition of PDF documents, no longer dependent on Ghostscript at runtime. - Recognition of polymers (different approach from POSRA - a separate tool focused on polymer recognition).
The new version is available at osra.sf.net
Please note that if you are building from source the dependencies have changed. OSRA now requires poppler (version 0.41) to process PDF files and a custom-patched version of OpenBabel to save polymer MOL and SDF files. The patched version of OpenBabel is provided at the above url. OSRA no longer requires Ghostscript to be installed.
