Dear Catherine,
You have missed word mask and : before residue number.
Try following (see p.262 in amber9 manual)
donor mask :610.O
donor mask :610.N
acceptor mask :720.N :720.HN
[the name of the hydrogen attached to the N is HN, I suppose?]
> Dear Sir/Madam,

> I could like to do the analysis for the hbond bonds between residues LYS610
> and SER720 only, but not all the LYS and SER in the PDB file. Could you
> mind to let me know what is the right approach to write the ptraj file?

> I tried :
>
> donor 610.O
> donor 610.N
> acceptor 720.N 720.NH
