[Chimera-users] Multiscale model of RNAP : fibrous aspect

Dear Elaine, I used the Multiscale Model tool to create a low resolution surface of the PDB 1L9U (TAQ RNA polymerase). The attached image is what I got with a resolution 4 : a fibrous structure. So, I wonder what such a fibrous aspect means or whether it means the tool has some difficulties to create the surface with this specific protein ? Thanks for your help Damien
