Hi,  This missing part can be displayed by "line" representation when I use "all" selection.However, when using ribbon to display it, an error message comes out:  ribbon code encounters an unusual structure, geometry may not look as expected. When using "cartoon" to display it, no information is shown in the  VMD text console bu it just doesn't display.
Best regards.

  Is this missing structure still not displayed when you use the "all" 
selection with one of the simple graphical representations such as "lines"?
Do you get any warnings in the VMD text console when the file is loaded?
