Hi All,
I want to perform a MD simulation of beta-cyclodextrin molecule. For
the system setup and force field I'm using Glycam06. The initial
coordinates of the molecule are known to me. The residue named 4GB
from GLYCAM_06.prep file I have chosen and create the force-field
using leap programme from AMBER. But while loading the *.inpcrd file
in vmd it is showing that there is no connecting bond between the
sugar ring 7 & 1 means there is no connectivity between the O4 (ring7)
& C1 (ring1). Whereas the other rings are connected properly. Also the
*.prmtop file shows that there are total 153 bonds (NBONH+MBONA) which
is expected to be 154. This also indicates there is the missing bond.
Could anyone pls suggest me what is the wrong with me & how to overcome it.
Any suggestion is highly accepted.
Thanks in advance,
Madhurima
