I'm trying to set up a system where I have a lipid bilayer and I want to
"attach" a small molecule to the surface so I can run dynamics.
I have generated the bilayer using VMD and I have built the small molecule and
have parameters and a topology for it. The problem I am having is in generating
the psf for the total system.
I have the *.pdb and *.psf for the bilayer and I can run that in namd; in fact,
I am minimizing it now as a test. However, when I try to generate a psf file,
because the bilayer is numbered "funny", some residues have the same number and
don't get converted to the new file. If I try to renumber everything by hand,
then it won't minimize (it gets to about 27 steps and then I get "weird numbers"
I'm wondering if anyone has encountered this before and what the workaround is.
