Dear Justin I confused. number of donors in donor.xvg file is 203. while, when use g_hbond: found 143 donors.
Select a group: 2 Selected 2: 'Protein_A' Select a group: 3 Selected 3: 'Protein_B' Checking for overlap in atoms between Protein_A and Protein_B Calculating hydrogen bonds between Protein_A (1042 atoms) and Protein_B (825 atoms) Found 143 donors and 439 acceptors Making hbmap structure...done. Reading frame 0 time 19500.000 Will do grid-seach on 14x14x14 grid, rcut=0.35 Reading frame 120 time 19980.000 Found 40 different hydrogen bonds in trajectory Found 69 different atom-pairs within hydrogen bonding distance Merging hbonds with Acceptor and Donor swapped 143/143 - Reduced number of hbonds from 40 to 40 - Reduced number of distances from 69 to 69 Average number of hbonds per timeframe 19.310 out of 31388.5 possible
