[AMBER] calculating HB lifetime

Dear Sir/Madam,

I would like to calculate the lifetime of hydrogen bonds in hydrated lipid
bilayer system.

I am interested to calculate 1) lipid-water HB lifetime and 2) lipid-lipid
HB lifetime.

When I look at the manual there is a command called *lifetime* (pg 556
AMBER 14) but I am not so sure how to use it.

I don't understand the meaning of <*dsetarg0*> file. despite it is saying
about data file. But which data file and how to obtain this file?

Anyway I tried something like below:



cpptraj topology << EOF

*lifetime out hb-LifeTime-bcmLyo25perR.out
HB_inBothLayer_001_128-bcmLyo25perR.tbl cut 0.5 greater*

EOF




with *HB_inBothLayer_001_128-bcmLyo25perR.tbl * is the output file of
hydrogen bonding.

But this fail to run.
I wish to get some here.

Regards
Vijay
