QM/MM input

[nagesh]

Hello Teo,

I thought, i was just using the default values in the reference manual
just for a check to obtain the spline interpolation convergence in
QMMM (but, the actual values in the manual are 1.E-10). i tried with
these values (1.E-10) , still got the same error.

do you think the values might still be bad for my system.

Regards,
nagesh
