Hi, Dr.
Here is the email from the mailing list.
Thank you,
Razil.

Subject: Re: [AMBER] Building Forcefield for Glycolipid Molecule
Razil,
some time ago we used a (somehow) similar system, namely trehalose with
two acyl chains. To be consistent within the ligand system (and to avoid
any cross-terms between forcefield borders), we decided to use only
Glycam atom types there and applied the Glycam charge parameterization
scheme.
If you are interested, have a look into the Supplementary material there:
https://doi.org/10.1038/s41598-018-23624-8
But I guess, Stéphane's work might be more related to your ligand system.
Good luck,
Anselm
