Dear Haiping Zhang, You can use the Modeller interface for building loops. First show the Sequence for that protein chain (menu: Tools… Sequence… Sequence). This sequence comes from the SEQRES in the PDB file and includes the whole sequence. The part that is missing from the structure is shown with a red outline box. To build the missing part, from the Sequence window menu choose Structure… Modeller (loops/refinement). The Modeller loop-building interface is described here: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/mo...> I hope this helps, Elaine ---------- Elaine C.

Dear professor Elaine C. Meng： I have a structure that miss some resides, I want to add a loop to fed the gap. How can I accomplish this by chimera? The structure is as bellow, I want to add some residus to the place where shows dot line. Thanks for your help.
