Dear AMBER users,
I need to do a minimization with frozen or restrained atoms.
When I put the following input (with restrained atoms):
minimization
&cntrl
imin=1, ntb=0,
cut=9.0, ntr=1, maxcyc=100000, igb=0,
&end
Restrained atoms
100
RES 2 5
RES 8 29
RES 33
RES 36 61
RES 63
RES 66 84
RES 98
RES 102 110
RES 112 119
RES 122 135
RES 137 141
END
END
I have the following error message:
5. REFERENCE ATOM COORDINATES

For the following input (frozen atoms):
minimization
&cntrl
imin=1, ntx=1, irest=0, ntrx=1, ntxo=1, ntpr=50, ntf=1, ntb=0,
cut=9.0, nsnb=10, scee=1.2, ntr=0, maxcyc=500, ntmin=1,
ibelly=1,
&end
Belly atoms
RES 1
RES 6 7
RES 30
RES 31 32
RES 34 35
RES 62
RES 64 65
RES 85 97
RES 99 101
RES 111
RES 120 121
RES 136
RES 142 145
END
END
I have the following error message:
Warning: Although EWALD will work with belly
(for equilibration), it is not strictly correct!

I think that the problem is with the format of the input file... I don't know what to do! Could someone help me please?
Thanks;
Julliane
