Yes, definitely! You can select any set of atoms that you like and then use an option to save selected atoms only. Or, you could delete all the other atoms and then save all the remaining atoms.
For example, you could select everything with chain ID C with a command (sel :.c) or the menu (Select… Chain… C) and then save with
(A) GUI: menu: File… Save PDB, with checkbox option “save selected atoms only”
- or -
(B) command “write” with “selected” option
With the other approach, you could first delete all the non-chain-C atoms. It could be done with the menu by selecting chain C, inverting selection, and deleting the resulting selection, or with one command:
delete ~ :.c
(delete NOT chain C)
I hope this helps,
