Hi,
I used the command g_hbond to find h-bond between  residues 115-118 and
water. Then I used g_analyze to find out the average and it gives the value
for the hbonds like this :-

                                  std. dev.    relative deviation of
                       standard       ---------   cumulants from those of
set      average       deviation      sqrt(n-1)   a Gaussian distribition
                                                      cum. 3   cum. 4
SS1   6.877249e-02   2.546419e-01   5.092839e-03       2.181    3.495
SS2   6.997201e-02   2.673450e-01   5.346901e-03       2.421    5.001

When I calculated the average manually, by taking the average of numbers in
second column of hbnum.xvg file, I got a value of around 13.5.. What is the
reason for such a large difference.

In another case, g_analyze gives avg values of aroun 6.9 for hbond between
two residues and when I calculated it maually I got the avg values as 6.8
>..

Whats the meaning of SS1 and SS2,?? Does it mean that SS1 refers to time
and SS2 refers to hbond numbers in the hbnum.xvg obtained from g_hbond
analysis ??

Please clarify these doubts..

Regards
------------
Bharat
