Thanks Elaine - I didn’t think of that, that is a very helpful tip.

>> At present chimera seems to represent missing segments in pipes-and-planks as a continuation of the chain rather than a break, which is a little confusing, e.g. check the following pair of snapshots (chain break in green section corresponds to missing 10aa loop):
