I only just ask for a brief explanation for each file, thanks anyway, the
gmx_helixorient.c could be a good solution.
Thanks again for your response.

Hi, I'm sorry to insist in my question but if somebody could answer or just to
send me some information or place to look for, I will be very thanked.
I imagine that these kinds of definitions are discussed in general
texts on (computational or experimental) modelling of proteins, so
that may be a good place to start with understanding what
g_helixorient might be calculating.

g_helixorient -h has some very basic information that could help.
Otherwise, I'm sure the GROMACS team regret that the documentation
is a bit lacking. Please do remember that GROMACS is a volunteer
effort. Because our resources are finite, it won't always be able to
be what we would all like it to be. The existence of the
g_helixorient tool is already rather more than you paid for, too
;-). Do consider using other simulation packages' analysis tool sets
- often trajectories can be inter-converted with little fuss. In
extremis, please consider reading the code of
src/tools/gmx_helixorient.c - but you'll need to be unafraid of the
mathematics of 3D rotation!
