[gmx-users] translate problem

[gromacs query]

Hi All,

I have membrane thickness along Z and want to merge peptide in membrane. I
need to translate peptide (say 10 Angs) along -Z to adjust its position and
used command like this:

editconf -f pep.pdb -c -princ -rotate 0 90 0 -translate -10 0 0 -o
new_pep.pdb

It seems that it does not move at all. But when I used '-translate -100000
0 0' then it moved a little along -Z. I am not sure whats wrong. Please
suggest. Also in VMD the center of pep does not pass through the principal
axis (slightly off center).

Thanks
regards,
JIom
