Hello,
I am sorry those were two different questions.. I wanted to know what
this statement actually mean?
"The set pressure should reflect whatever system you are trying to model."
You haven't fully explained what exactly you're trying to do yet, so I'm taking
a stab in the dark. Let's say you're trying to simulate a benchtop experiment
with a protein in solution over a heating mantle at 350 K. The pressure is 1
atm under such circumstances (NPT). Now let's say you want to simulate the
behavior of a protein solution in a bomb calorimeter (constant volume) at 350 K.
The pressure is not likely to be 1 atm under such circumstances (but then too,
you'd use NVT instead of NPT, but maybe after NPT equilibration at whatever the
necessary pressure is). Without a fully detailed description of what you'd like
to accomplish, I'm going to stop guessing.
You've asked a lot of scattered questions about different topics, which makes it
less efficient for people to help you and less clear for you to understand what
we're trying to communicate back, even if it is somewhat generic.

Thank you

I don't see the connection to my comment about pressure, but I'll
address this anyway. There is no temperature during EM. Hence with
"gen-vel = no" then no velocities are generated. The settings for
gen-temp and gen-seed are defaults that are assigned when none are
provided in the input .mdp file.
I seem to recall that a pressure term is written during EM, but it
is largely meaningless.
