[ccp4bb] a question on presenting 3-D crystal structure in the paper

[Acoot Brett]

Dear All,
 
I want to use dash line to present the salt bridge in a crystal structure in 
the paper publication, for example the salt bridge formed between Glu (OE1 and 
OE2) and Lys (terminal N). 
Do you suggest I only draw a single dashed line between the terminal N of the 
Lys and the closer atom to N among the Glu OE1 and Glu OE2 in the final 
publication, or in the final publication I will have 2 dashed lines, one is 
between terminal N of Lys and OE1 of the Glu, the other is between terminal N 
of Lys and OE2 of the Glu, supposing the distance of both the 2 dash lines are 
within the acceptable range for salt bridge?
I am looking forward to getting a reply from you.
Cheers,
Acoot
