Hi.
Did you inspect the contents of hbmap.xpm? There's a header followed by
matrix data. You can think of the matrix as ones and zeroes, represented
by the characters 'o' (= one) and ' ' (space = zero). As such, the rows
of the matrix are vecors containg ones and zeroes. Two such vectors can
easily be multiplied elementwise. If you write a program or script in
your language of choice, that reads the matrix data as ones and zeroes
instead of 'o's and ' 's, and then multiply the vectors elementwise,
then that part of the job is done. I'd do it using python, but
everything form matlab to C will do.
Is it clearer now?

Dear Mark and gromacs users
thanks for your time and consideration.
you said by multiplying the existence functions for hbonds between protein and
water and the hbonds between water
and DNA, then using Justin's script, I can obtain percentage each water medited
hydrogen bond during trajectory.
and also you said I need to create a corresponding index file too.
I don't know where should I start for multiply two existence functions?
please explain about it more.
any help will highly appreciated.
