[gmx-users] hbond analysis

[Urszula Uciechowska]

Dear gromacs users,

I am having some problems with hbond analysis using gromacs. I am
interested in hbonds between certain amino acids for example: LYS256 and
nucleic acid that has number 2 in my files. I generated the index file
which contains r256 and r2 by running make_ndx -f gro -o out.ndx
then I run g_hbond
g_hbond -f traj.xtc -s .tpr -num hydrogen-bonds-protein.xvg

My xvg file did not contain any hbond between those amino acids, which is
not true. I do not know what went wrong. Could anyone suggest me
something?
Is there any other way to run the hbond?

Is it possible to use the xtc trajectory and run hbond anlysis in ptraj?
or can I convert it somehow?

Best regards
