Dear Prof. David van der Spoel,
Thank you very much for your helpful response. I am sorry for further
asking.
I tried to field information during the MD using -field option. It gave me
*****************************
@ title "Applied electric field"
@ xaxis label "Time (ps)"
@ yaxis label "E (V/nm)"
@TYPE xy
0 0.5 0 0
0.001 0.412668 0 0
********************************
Then,
gmx potential gave the field.xvg file?
This filed.xvg contains box and field.
*********************************
@ title "Electric Field"
@ xaxis label "Box (nm)"
@ yaxis label "Field (V/nm)"

3.196269750595093 0.1159880973735597
*************************************
Do you mean this field.xvg output?
I am sorry again.
Best regards,

Why don't you try to play around and check the output file field.xvg to
see what frequency you get?
