Hello to All Namd-l subscribers,
I didn't want to start a discussion here so I apologize spamming your email and
I still think that if someone does not really answer a question or want to help
solving the problem, she/he should not answer the email. The level of simplicity
of a problem is subjective. I witnessed rude or irrelevant replies to some
other problems which seem challenging.
I don't want to make this personal and I also don't think "all" of the replies
from the people who sometimes send mean and irrelevant emails are not useful. So
I really do not want to discourage them to send all of their replies. :o).
ABOVE ALL NATIONS IS HUMANITY.
"What matters - all that matters, really - is the will to happiness, a kind of
enormous, ever-present consciousness. The rest - women, art, success - is
nothing but excuses." - Albert Camus
Cause life is meant for living. Yaki-da ;o)

it is meant to discourage people to ask questions without
spending some effort on their own. it has become common
practice to rather spew out a few random questions (ideally
cross-posted to many mailing lists) before even thinking about
what the answer would be.
there is a very important relation between a question and its answer:
the answer can on average only be as good as the question.
thus if you want to see a "better" answer, you may have to ask
a "better" question.

an important part of learning is to find the right forum
to ask the right question.
this is not a forum to ask questions about elementary MD issues.
it is about the NAMD simulation program. one has to assume that
a person asking questions show that he/she has at least spent
some effort to "make his/her home work".
while it may sound rude to not answer a question and send
somebody elsewhere, i am convinced - from lots of personal
experience i might add - that this is the by far best way to get
the kind of help the original poster is looking for. behind this
simple question are looming many details (and more questions)
that also need to be answered and that is effectively impossible
to do via e-mail. i have been there. with some minimal effort on
a search engine, however, lots of useful resources can be found,
even by a beginner, but then it is _essential_ to find a local expert
to discuss (or take classes, participate in proper tutorials, and so on).
other than that. i can only encourage you to prove me wrong
and answer the questions asked and see where this leads.
