Kinetic Energy frm MDEnergy (energy evaluation tool)

Hi all,
I have tried to calculate the kinetic energy of the selected atoms by
MDEnergy. In order to calculate this, I have mentioned the following in
the command line:
mdenergy -vel file-vel.dcd -dcd file1.dcd -psf file1.psf -par par-file1
-beg 1 -end 400 -sel file2.ind -kin
file-vel.dcd velocity dcd file
file1.dcd structure dcd file
file1.psf psf file
par-file1 parameter file
file2.ind selection file (which is the index file--the kinetic
energy is to be calculated for this selection)
This is the calculation for 400 frames.

However, the output file is showing *zero kinetic energy for* each frame
(kinetic = 0).
Please explain me, why I am getting the value of kinetic energy as "0"
for each frame ?
I would highly appreciate any kind of help regarding this.
