Hi Saleh,
It is still to be released. I added a lookup in case it is released during
the year, so right now while you can pack systems with sphingomyelin, there
are no parameters for it. Callum (in CC) might give us some idea about the
potential release, hopefully we get them soon :D.
At the moment, you can try to parametrize the structure packed by
packmol-memgen yourself (you can get a plain pdb to have a framework to
work on by using the --keep flag; most intermediate files including the
lipids should stay in your folder then).
Best regards,
