[gmx-users] % of existence of hydrogen bond

[Moutusi Manna]

Dear all,
        I am dealing with a POPC+PEPTDE+WATER system. Basic residues of the peptide make hydrogen bonds with lipid headgroup (as reflected from g_rdf analysis) and the number of hydrogen bonds formed can be calculated from g_hbond program. Now, i want to calculate the % of trajectory time for which a bond between a particular group (say LYS and lipid headgroup po4) exist. -hbm gives a .xpm matrix, on solving (using xpm2ps) that i got a .eps file, which is a picture file of h_bond existence map, but the data sheet is not given.
Can any one help me to solve this problem?
With regards,
