Hi, I tried to use phenix.autobuild to generate a SA-omit map around a non-protein residue but I didn't succeed. Can someone give me a recipe? (perhaps with file from the ligand fit examples.... ;-) ) Thanks. Have a nice day. Mathieu. ____________ Mathieu Coinçon Biochemistry PhD Student Université de Montréal (+1)514-343-6111 #5352
