Dear all,

I am trying to do some two phase simulations with Decane molecules and some
other smaller molecules.

When I did simulations with smaller molecules, I specifies the properties
based on each atom, while I just realized it is really not desirable to do
it with Decane molecules ( 34 atoms each molecule).

I am wondering if anyone could provide one coordinate file and the itp ( or
.top ) file for the Decane simulation if you have ever done it before.  I
did not find very detailed Decane molecule models.


You should probably mention what force field you're trying to work with. For a simple alkane like decane, writing the necessary .rtp and .hdb (if necessary) entries is fairly trivial. Then just let pdb2gmx do all the work assembling the whole topology.
