[gmx-users] Help again: the projection on normal modes

[Tanping Li]

Dear all,
 

I am testing the INM analysis. I get the eigenvector
file eigenvector.trr; and then do the projection on
INM normal modes by the command:
 
g_anaeig -proj -v eigenvector.trr -f c.gro -proj
proj.xvg
 
 
But what I get from proj.xvg is pretty stange. Except
the first few values, all of them are 0.

Is it fine, or I misunderstood how to use g_anaeig?

somtime.
