Re: formyl and ethanolamide parameters and topology

I normally use the following protocol:

1) Search for your molecule at Pubchem and copy the SMILES format of it.

2) Go to the Zinc database ( and use the SMILES format to search and download the *.mol2 version of the molecule.

   Alternatively uou may use Quimera software to generate Hydrogens and save as *.mol2 from a simple *.pdb file.

3) Then, go to the Swiss Param ( and use the *.mol2 file to generate parameters and topology of interest.

OBS: Note that inside of the topology file the name of the residue will be LIG, independently of the molecule, and you must change it before use.
I hope it can help.
