On the subject of NCS chains, Paul, I note that you are still using
SSM superposition in determining NCS operators (unless it's been
changed _very_ recently), rather than the LSQ algorithm which would
preserve the sequence register. SSM gets the wrong answer in some
cases, eg in some coiled-coil proteins such as BAR domains, where an
out-of-register SSM superposition can give a lower score than the in-
register one, and of course the correct NCS must be in register.
You did say quite a long time ago that you going to change this :-)
Best wishes
