Hi, I selected several residues in an icosahedral viral capsid and want to save the corresponding pdb. However, whatever name I try to give this selection I receive the error "You must provide a file name that contains either $name or $number, which will be changed to the model name or model number (respectively) in the final saved file name". Can you please give me an example of a valid name! The viral subunits are 6sk5.pdb1 (#0.1), 6sk5.pdb1 (#0.2), and so on. I have no clue what I should call this selection for it being accepted. Thanks a lot, Dieter ------------------------------------------------------------------------ Dieter Blaas, Max Perutz Laboratories Medical University of Vienna, Inst. Med.
