I have modified the gmx x2top tool so that it can also be used to generate Gromacs .top or .itp topology files for the MINFF forcefield (for oxides/hydroxides and many (clay)minerals), using simple .n2t files now available in the MINFF distribution. Custom n2t files can easily be edited manually or printed via routines in the atom (MATLAB) or atomipy (Python) libraries.

This new and patched x2top tool (should still be back-compatible) have been tested for a few periodic and triclinic crystal slab systems and seems to work well.
