Hello,
I have done a simulation using Gromacs 4 (4.0.2) and I would like to have a 
trajectory were the protein is fitted to the first structure (to mantain the 
exact orientation).

When I have tried

echo 1 1 0 | trjconv -f production_1_3.xtc -s production1.tpr -center -fit 
rot+trans -pbc mol -o production_1_3_fit.xtc

visualizing production_1_3_fit.xtc I can see that the protein is fitted, 
however there are a lot of "holes" into the water box. It seems like the pbc 
were not correctly applied. I have tried changing a lot of options (-pbc res, 
-boxcenter rect,...) but nothing works.

The options

trjconv -f production_1_3.xtc -s production1.tpr -center -boxcenter rect -fit 
rot+trans -pbc mol -o production_1_3_fit.xtc

do not produce any hole in the box of water, but the box entirely moves around 
the protein, and sometimes it is outside of it and not solvated.

I have also tried using Gromacs 4.0.4, but the problem is still the same.

Could anybody give an idea of how solving it, please?

Thank you very much for your help.

Best wishes,
