In addition to Marks pointers, the sphingos are tough little bastards
(pardon me), in terms of parameterization. There are people working on
parameters which are probably more experienced with parameterization,
and it's not without reason that good parameters have not yet been
However, I've seen a study using MD on sphingomyelin, with parameters
fiddled in the same way you did. You can try to dig the literature,
but don't set your hope on getting correct behaviour (e.g. a correct
area per lipid).
