Thanks Tim for the timely tips. I haven't tried Arp/wARP but will follow
your recommendation right away. I haven't installed Resolve yet but will
look into it and Buccaneer as well - I was having fun modeling some of the
apparent fragments into the density but with a protein so big, I ran
exhausted before long ;p)... Due to the same fatigue, I wasn't patient
enough to rename the Chain ID of the updated fragments. Practically, it
seems that* I have to rename the chain ID before "Renumber Residues" as they
are two different entities on the menu.* Actually, would Coot authors
consider adding "Change Chain ID" into the "Renumber Residues" window so
that I I could do both changes on the fly? Thanks, Jacob Wong
