Hi Mark, You can use the "Fixed atoms..." widget in the toolbar (below regularize) to do just that - click on it and you can set the fixed atoms.
The regularize command (without a map) tends to move things more than I think they should. Perhaps the end atoms should be fixed. How would one restrain atoms to their starting coordinates? From the old days I recall Frodo's "REFI" command being better behaved. Any thoughts on this?
