[Chimera-users] where is "Save each fit when doing multiple alignments" button

Dear all,I am studying the chimera tutorial "fitting to segments" of  Segger segmentation tutorials from Greg Pintilie at NCMI (http://ncmi.bcm.edu/ncmi/software/segger/docs_fitting). In the last paragraph, the tutorial states that to align the structure to multiple regions, one needs to check the "Save each fit when doing multiple alignments" button. But where is this button? I cannot find it in the "Fit to Segments", "Segment Map" or other dialogue boxes. Could you tell me where I can find it?Best regard,Yeping Sun Institute of Microbiology, Chinese Academy of Sciences
