I'm not sure that the conversion tool [top2psf] is coping with the .top file and its three .itn include files. I have tried numerous work around's for include files [by pulling them out into the .top file], but I cannot seem to find a way to get the .psf, .gro and .xtc formats all loaded correctly into VMD. Native conversion of the .top [includes extracted] into .psf doesn't work and nor does converting each .itp file individually and concatenating.

Do I have to describe each and everyone of the lipids in the system and the same question to the solvent. Apologies for the ask, but I could find nothing other than quite simple molecules with no solvent as examples for .psf.

grompp -pp can write a post-processed .top file that does not have any 
#include statements. Hopefully that is suitable for top2psf.pl.
