[gmx-users] g_anaeig -proj

Hi everyone,

please I'm doing for the first time a covariance analysis.
I followed this tutorial:

But I don't understand. -proj gives the projection of the trajectory on the
first eigenvector, so I was expecting to have new coordinates for each atom
or each residue. Instead, I get a .xvg file saying:
""projection on eigenvectors (nm)"
@ xaxis  label "Time (ps)"
yaxis  label "vec 1"

Please can anyone tell me what this actually means? What data is in
nanometers? What does gromacs project?

Sorry if my question is stupid, but I can't find the answer.

Thank you.
