| There might be something wrong with the ptraj's interpretation of the selection command.

|

| Please use

| donor mask :MTS_at_O1

| acceptor mask :MTS_at_N1 :MTS_at_H7

|

| instead of

| donor MTS O1

| acceptor MTS N1 H7

|

| If you cannot fix the problem by doing so, please let me know.

    I did as you suggest, my input file is now

trajin file1.mdcrd

rms first out file1.rms :GSU_at_C1,C2,C3,C4,C5

donor mask :MTS_at_O1

acceptor mask :MTS_at_N1 :MTS_at_H7

hbond distance 10.0 donor acceptor series hbond

I put "distance 10.0" just for test as I know that the atoms involved are at a distance less than 6.0 Angstroms

during the simulation, and the answer is

[...]

"PTRAJ: donor mask :MTS_at_O1

Mask [:MTS_at_O1] represents 1 atoms

PTRAJ: acceptor mask :MTS_at_N1 :MTS_at_H7

Mask [:MTS_at_N1] represents 1 atoms

Mask [:MTS_at_H7] represents 1 atoms"

[...]

"data will be sorted, intra-residue interactions will NOT be included,"

 

   so I still cannot list intra-residue h-bonds.

    Have you any other suggestion?

                                                                                        Thanking you in advance
