Hello AMBERs -

Thank you all for the answers re: defining groups in AMBER - your
sugggestions worked, but I'm encountering now another problem: AMBER
inexplicably complains about and end-of-file in th einput, although it
has the two END statements, as required:

  ntt=1, tempi=0., temp0=5000., tautp=2.0,

  ntc=2, tol=0.00001, dt=0.002, ntf=2, ntcm=1,
  nstlim=25000, ntwx=500, ntpr=500,
