Hi, Amber Users,
I can combine my two pdb files now: one is sugar
produced by Leap; another is lipid, and I used
antechamber to get
.prepin and .frcmod files. There is an ether bond
(O-C-O) between one sugar and lipid tail. I used “
bond “ command to connect them.
Although I modify the .frcmod files produced by
antechamber for lipid like the following:
# remark goes here
MASS
BOND
OS-c3 386.000 1.425 # Jcc, 7, (1986), 230
ANGLE
OS-c3-c3 67.800 108.7
OS-c3-h1 50.900 106.2 # JCC,7, (1986),230
OS-c3-h1 50.900 106.2
CG-OS-c3 100.00 117.6 # JCC,7, (1986),230
DIHE
IMPROPER
NONBON
I still got the following warning:
Could not find bond parameter for OS-c3
Could not find angle parapeter: OS-c3-h1
OS-c3-h1
OS-c3-c3
CG-OS-c3
I don’t understand why it cannot recognize the
parameter
I give. Anyone can give me some suggestion for this,
and so I can get the .top and .crd file, and then go
for vacation J.
Thanks in advance
