Hi Tiger, Nick is largely right. The cause for the link to show up is that pymol just traces through all c-alphas in the object, regardless of chains or distances. So, selecting the linked residues and hiding the trace should solve your problem. Also, creating two files will do the trick. Alternatively, you can create two objects and draw the trace for each of these.
