Hi Mark.

Wait a second, you mean that editconf would allow me to have both charges and masses on a .pdb file directly from command line (having other matters asking for my presence absolutelly now, so please forgive me if this message becomes somehow strange)

So, I would have atom names, number of molecules types, number of molecules of each type, number of atoms of each molecule type, coordinates, charges and masses on a .pdb file, correct?
no just atoms and charges.




But, still, where could I then easilly get the box type and sizes, as well as simulation times?
box is in xtc file.

You could make your life easier by learning some C, unless you hae to link the trajectories to a big fortran library. By the way you can also trjconv -f k.xtc -o l.g87 which you can read using 10f8.3


Thanks a lot for all the help, and sorry for this punctual hurry here.

Sincerally yours,

Jones

    Yes, I now see that editconf has that ability, and Jones can fill in the
    masses himself, so he doesn't need to parse the .tpr at all.
