What gets me in this thread is the "implication" that one has to be able to write code in order to do MD, use NAMD, do PCA or, better yet, even be a computational chemist.
Personally, I'd rather know why H2O is a liquid and H2S isn't than to be able to "write code".
A person that knows why water is a liquid when it shouldn't be is a chemist (or physicist) while the latter is a programmer.
Those of you that want to imply we should all be able to write code should go and be on another list.
A REAL chemist uses the code (or program) that helps him to be solve the particular problem he's working on or is interested in.
We're not all programmers on this list.
I've done PCA and I used NAMD to do my MD and used a script written in Matlab.

*Real* programmers use matdcd
(http://www.ks.uiuc.edu/Development/MDTools/matdcd/) and do it in
But gromacs is the fast and easy way way.
