Dear all,
I have a file and I want to find the salt bridges. But when I click the
'Find Salt Bridges', then a pop-up shown and the message is:

No oxygens of acidic amino acid residues were found in the given selection.
No oxygens of acidic amino acid residues were found in the given selection.

    (command bound to event)

It says that my file doesn't have oxygens, but when I manually check the
oxygens using graphics representations, there are a lot of oxygens on my
protein.

Can you help me to solve this problem?
Thank you.
