PICTO is a Graphical tool to sketch new molecules, as well as view and modify existing molecules. The focus is primarily on small molecules, but it is not limited to small molecules. 2D molecular depictions in PICTO are provided using OpenEye’s OEDepict toolkit.
PICTO is comprised of three sections: A main sketcher with a toolbar, a secondary sketcher for SMARTS queries, and a text based input and outputs section. The main sketcher is directly correlated to the text based input and output section.
The input textbox can depict molecules utilizing SMILES, InChI, or a compound name. Beneath the input textbox are three outputs: Isomeric SMILES, InChI, and Compound Name. The Compound Name output has five naming styles: OpenEye (default), IUPAC, Traditional, Systematic, and CAS.
