Thanks for reply

I have used these atom mask specification but again getting same warning

PTRAJ: acceptor mask :20-280.N :20-280.H
Mask [:20-280.N] represents 261 atoms
Mask [:20-280.H] represents 253 atoms
WARNING in ptraj, acceptor: There is not a 1-1 correspondence between the
atom selection in the two masks :20-280.N and :20-280.H which contain 261 and 253
atoms respectively. Ignoring...
