Hello. I followed your advice and tried different versions of GROMACS (4.5.6, 4.6.2). All of them give one and the same error:
Program mdrun, VERSION 4.5.6 (or 4.6.2) Source code file: /home/timofeev/GROMACS/gromacs-4.5.6/src/mdlib/qmmm.c, line: 710 Fatal error: Ab-initio calculation only supported with Gamess, Gaussian or ORCA. If I understand right, it occur because the GROMACS doesn't receive a value of qm/mm program.
