Dear Giovanni, This list is for questions related to Chimera. Sorry, Chimera does not have chemical diagram sketching. The most similar thing is that you can get a diagram by entering a SMILES string using "Structure Diagram" (in menu under Tools.. Utilities). <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/diagram/diagram.htm...> Maybe you could try asking your question in a more general forum such as the Computational Chemistry List, CCL.net Regards, Elaine ---------- Elaine C.

Dear List, kindly would like to know if there is an open-source software for advanced molecular modeling for use with Linux (Ubuntu, CentOS, Debian) along the lines of ChemDraw or ChemSketch. Thanks for Your attention. Best Regards, Giovanni Ortosecco
