Hi.<br>
<br>
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.<br>
<br>
Is it clearer now?<br>

<pre style="font-family: arial,helvetica,sans-serif;">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.
