Hi,
I am trying to do a simulation using phosphatidylglycerol (PGR) in
lipid14 (+lipid14_supp). Unfortunately, when I try to write out a
parameter file of my molecule in leap, the following message occurs:
"Building topology.
Building atom parameters.
For atom: .R<PGR 1>.A<O35 24> Could not find vdW (or other) parameters
for type: oH
For atom: .R<PGR 1>.A<HO5A 25> Could not find vdW (or other)
parameters for type: hO
For atom: .R<PGR 1>.A<O36 38> Could not find vdW (or other) parameters
for type: oH
For atom: .R<PGR 1>.A<HO6A 39> Could not find vdW (or other)
parameters for type: hO
Parameter file was not saved."
When I look at the lipid14.dat file, there are no atom types or
parameters for the alcohol function (oH and HO) in PG. In lipid11.dat,
they are present. However, if I try to copy the atom types and vdw
parameters to lipid14.dat, leap doesn't recorgize any atom types
anymore, not even the other ones.
Is it possible that there are no atom types for the alcohol function
in the lipid14 version of PGR? Can anyone help me fix this?
Kind regards
Niels
