Dear all,
We would like to do some MD simulations for membranes. We have a big
amount of lipids (POPE as written in the pdb file) but I can not find
a way to obtain the amber topology and coordinate files with
xleap/tleap in first place. It seems to be that amber is not reading
the corresponding POPE lines from the .pdb file. I went through the
amber .lib files in oder to have some hint about how to edit the .pdb
file, but I can not find anything there about the lipids.
Here I copy below some of the lines form the .pdb file we suppose we
should change (one residue). The question is if somebody knows how to
change these lines in order to have a pdb file readable with amber?
Thanks in advance for any feedback!
Regards, Alex
