There is no isCoil attribute. If a residue is not helix and not sheet then it is coil. So to set residues 106-121 to coil use setattr r isHelix 0 :106-121 setattr r isSheet 0 :106-121 Tom On Nov 11, 2013, at 3:58 AM, Puey Ounjai wrote:

Dear Tom,

I am wondering if there is any way to set attribute to coil for particular residue just for rendition? I tried command "setattr" it works perfectly for helices and sheet but I dont know if option isCoil do exist

Thanks, Puey
