First, make a single PDB file that has everything you want (or that you
had in gromacs.) Put TER cards between glycolipid molecules if they are
not already there.
Second, run tleap: load the mol2 files, the leaprc.water.tip3p, any
other units you will need. Then use loadPdb to load your pdb. If you
pdb file was from a periodic simulation, then use
set x box { 32.5 50.0 37.8}
where "x" is the name you gave in the loadPdb command, and the numbers
are the box lengths. (If you have a non-rectangular box, you will have
to learn how to use ChgBox.)
Be sure to visualize the system, check visually that the bounding box is
in the correct place, check the initial structure for bad contacts, etc.
...hope this helps....dac
