I think Tsjerk has already given you a nice, detailed explanation. The problem
is you have not done the leg work of reading the relevant manual sections.
In general, as I say several times a day it seems, when asking for free help,
make it easy: show exact error messages (copied and pasted from the screen
output) so we know exactly what's going on.
Basically, you will need to define parameters for the TFE molecule in an .itp
file (I suspect your previous message was in relation to this fact?).
Furthermore, parameters for TFE already exist in $GMXLIB/top. If you do not
want to use these, use this tfe.itp file as the template for what you create.
Tutorial material (some of which Tsjerk already recommended to you) and the
manual/wiki will provide you with the answers you need.
