The SMILES string should be enclosed in quotation marks. : " SMILES-string"Įnter SMILES string and use it in place of an input file. If only input and output files are given, Open Babel will guess the file type from the filename extension. For more information, se the Open Babel web pages. Open Babel is also a complete programmers toolkit for developing chemistry software. Obabel is a cross-platform program designed to interconvert between many file formats used in molecular modeling and computational chemistry and related areas.
