[gmx-users] problem regarding .top file generated by genbox

I suspect you have an error with the order that you have included the relevant
.itp files within your topology.  It would be helpful to include a snapshot of
your topology which illustrated the order in which these files are included.

Also, if you are asking whether your commands are right or not, you should
include your actual commands, otherwise our default assumption is "probably
not." :-)
