Hi,
I just recompiled amber and it seems to be working well, i changed the
maxatoms from 5,000 to 50,000 now when i create the RST.f file i get this
[Taufik.sb2051B-9 CEBP8]$ makeDIST_RST -upb fixbond -pdb CEBP8.pdb -rst
RST2.f
# makeDIST_RST
Currently configured for up to 50000 atoms
Using MAP file /usr/local/Programs/amber10.09/dat/map.DG-AMBER
The number of atoms has changed. The output (RST.f and RST2.f) are
exactly the same, before and after modifying global.h
yet when i try
>sander -O -i minimize.in -o CEBP8.out -c CEBP8.inpcrd -p CEBP8.prmtop
-r CEBP8.rst
i get >At line 841 of file _nmrcal.f
Fortran runtime error: End of file
not sure what is wrong, my minimize.in file is
CEBP8 minimization of 20,000 steps
&cntrl
imin = 1,
maxcyc = 20000,
ncyc = 10000,
ntb = 1,
ntr = 0,
cut = 10,
nmropt = 1,
/
&wt type='REST’, istep1=0,istep2=5000,value1=0.1,value2=4.0, /
&wt type=’REST’, istep1=5001,istep2=20000,value1=4.0,value2=4.0, /
&wt type=’END’ /
DISANG = RST2.f
Thank you for your help,
Taufik
