Hi Tsjerk, Thank you again for your replies.
I have found the line in the manual and probably we are talking about the same thing. Something last that I have just observed, it happens that after the simulation some molecules of the crystal on the Y boundaries form new bonds with the other side molecules of the crystal. They appear to be close enough to form bonds, so could the reason for that be the gromacs or a suspicion I have that the box length on Y is slightly smaller than it should ?

The box is exactly the same. The reason for the reordering is that Gromacs puts the atoms in the corresponding rectangular brick, which is more convenient computationally. Check the section in the manual on PBC. It's explained there.
