Hi,
I am using AMBER 7 to simulate a carbon nanotube. The nanotube has 576
carbon atoms. I want to use the potential parameters of "CA" in parm99
for each C atom in the nanotube. I generated the pdb file by BABEL, it
looks like
ATOM 1 C UNK 1 5.239 1.404 0.000 1.00 0.00
ATOM 2 C UNK 1 5.378 0.708 1.230 1.00 0.00
ATOM 3 C UNK 1 4.303 3.302 1.230 1.00 0.00
ATOM 4 C UNK 1 4.697 2.712 2.460 1.00 0.00
ATOM 5 C UNK 1 2.712 4.697 0.000 1.00 0.00
ATOM 6 C UNK 1 3.302 4.303 1.230 1.00 0.00
ATOM 7 C UNK 1 0.708 5.378 1.230 1.00 0.00
ATOM 8 C UNK 1 1.404 5.239 2.460 1.00 0.00
ATOM 9 C UNK 1 -1.404 5.239 0.000 1.00 0.00
ATOM 10 C UNK 1 -0.708 5.378 1.230 1.00 0.00
ATOM 11 C UNK 1 -3.302 4.303 1.230 1.00 0.00
.........
with the necessary connection info. Can you suggest an easy way to modify
this pdb file so that leap can recognize the residue and load in the
correct potential parameters?
Thanks
