[gmx-users] cholesterol

[Preeti Gupta]

Hi All,

I am new user of gromacs and i want to simulate cholesterol + DOPC as my final 
year project.
firstly i tried gromacs with cholesterol, for which i have downloaded 
cholesterol pdb and itp file from gromacs site by Monika Hoeltje. 

i m getting the following error- Residue 'CHOL' not found in residue topology 
database.
I tried PRODRG for generating cholesterol topology file and coordinate file, 
but 
still i got the error-
invalid directive of atomtype.

can someone give me charmm residue topology file for cholesterol or with some 
solution.

Thanks in advance.--
